Removed unused 'Rx::Init()' function. Added '\n's onto the end of '\r's that were by themselves. Initialised Rx::helpEnabled to true in constructor. Added 'Clide::Comm' class which will serve as a base class for both 'Clide::Tx' and 'Clide::Rx'. Added 'help' command functionality, which is automatically added to Clide::Rx if the macro '#clide_ENABLE_AUTO_HELP' is set to 1.
