Refactored RadioMediumObservable to RadioTransmissionObservable because of its function
Added correct RadioMediumObservable and updating in AbstractRadioMedium, DirectedGraphMedium and MRM
Added some documentation
The .2mg image format contains a header which is missing from our file. So our file is rather a .po image.
I opted to not add the .2mg header as it is only necessary if the metadata it contains differs from the values "guessed" when using the "naked" .po image format. On the other hand there are image file consumers not understanding the .2mg image format.
- By end of Jan 2014 SuperTweet.net was shut down (http://supertweetnews.140plus.com/). So Breadbox64 has come to an end for sure :-(
- The email app - or rather email sending app as it is SMTP only - can't be used anymore since nowadays everybody uses some "strong" authentication for SMTP session logon (thanks NSA).
- The ftp client app isn't very useful as it supports only download - for which the WGET app is almost always more useful for. But more important it doesn't support PASV which is more or less the only supported mode nowadays (especially over NAT).
* Fix CCA detection in Cooja in the case when the receiver swicthes on the right channel during an ongoing transmission. Always add a connection on transmission, even when the channel is not correct. Initially the connection is in a dormant state; this mimics what Cooja is doing when the receiver radio is turned off;
when the receiver is turned on and switched to the right channel, `updateSignalStrengths()` is called, and the connection starts to recieve PHY-level traffic.
* Add "channel" property for DGRM edges.
* Avoid cross-channel interference on DGRM and MRM radio mediums
In the previous implementation a click event was triggered when the
button was pressed.
This implementation allows to set and release buttons independently both
by mouse clicking and by key typing.
SIM_CONTROL_PLGUIN are handled like SIM_PLUGIN, with one exception.
If the simulation is started with -nogui=<simfile> than it is checked
if a controlling plugin is loaded. If not, the simulation terminates
with an error message.
