Remaining LaTeX macros

Browse source 
Added the remaining LaTeX macros from our list.
What remains is to decide on how to resolve the conflicting definitions of

   \binom{}{}

and to supply suitable characters for

   \righttoleftarrow
   \lefttorightarrow

The plain TeX syntax {A \over B} is unsupported (passed through verbatim, and will cause a LaTeX error).
