+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent

+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+   APPENDIX: How to apply the Apache License to your work.

+
+## Beautiful math in all browsers
+
+MathJax is an open-source JavaScript display engine for LaTeX and MathML
+that works in all modern browsers.  It was designed with the goal of
+consolidating the recent advances in web technologies into a single,
+definitive, math-on-the-web platform supporting the major browsers and
+operating systems.  It requires no setup on the part of the user (no
+plugins to download or software to install), so the page author can write
+web documents that include mathematics and be confident that users will be
+able to view it naturally and easily.  Simply include MathJax and some
+mathematics in a web page, and MathJax does the rest.
+
+Some of the main features of MathJax include:
+
+- High-quality display of LaTeX and MathML math notation in HTML pages
+
+- Supported in most browsers with no plug-ins, extra fonts, or special
+  setup for the reader
+
+- Easy for authors, flexible for publishers, extensible for developers
+
+- Supports math accessibility, cut-and-paste interoperability and other
+  advanced functionality
+
+- Powerful API for integration with other web applications
+
+See <http://www.mathjax.org/> for additional details.

+  //  Patterns to remove from before and after math script tags.  If you are not
+  //  using one of the preprocessors (e.g., tex2jax), you need to insert something
+  //  extra into your HTML file in order to avoid a bug in Internet Explorer.  IE
+  //  removes spaces from the DOM that it thinks are redundent, and since a SCRIPT
+  //  tag usually doesn't add content to the page, if there is a space before and after
+  //  a MathJax SCRIPT tag, IE will remove the first space.  When MathJax inserts
+  //  the typeset mathematics, this means there will be no space before it and the
+  //  preceeding text.  In order to avoid this, you should include some "guard characters"
+  //  before or after the math SCRIPT tag; define the patterns you want to use below.
+  //  Note that these are used as regular expressions, so you will need to quote
+  //  special characters.  Furthermore, since they are javascript strings, you must
+  //  quote javascript special characters as well.  So to obtain a backslash, you must
+  //  use \\ (doubled for javascript).  For example, "\\[" is the pattern \[ in the
+  //  regular expression.  That means that if you want an actual backslash in your
+  //  guard characters, you need to use "\\\\" in order to get \\ in the regular
+  //  expression, and \ in the actual text.  If both preJax and postJax are defined,
+  //  both must be present in order to be  removed.
+  //
+  //  See also the preRemoveClass comments below.
+  //  
+  //  Example:
+  //      preJax: "\\\\\\\\",  // makes a double backslash the preJax text
+  //    or
+  //      preJax:  "\\[\\[", // jax scripts must be enclosed in double brackets
+  //      postJax: "\\]\\]",
+  //
+  preJax: null,
+  postJax: null,
+  
+  //
+  //  The CSS class for a math preview to be removed preceeding a MathJax
+  //  SCRIPT tag.  If the tag just before the MathJax SCRIPT tag is of this
+  //  class, its contents are removed when MathJax processes the SCRIPT
+  //  tag.  This allows you to include a math preview in a form that will
+  //  be displayed prior to MathJax performing its typesetting.  It also
+  //  avoids the Internet Explorer space-removal bug, and can be used in
+  //  place of preJax and postJax if that is more convenient.
+  //  
+  //  For example
+  //  
+  //      <span class="MathJax_Preview">[math]</span><script type="math/tex">...</script>
+  //
+  //  would display "[math]" in place of the math until MathJax is able to typeset it.

+  showProcessingMessages: true,
