First real commit of sources.  Stuff builds (sorta, I cannot check in the CUSBSA.cpp/.h files due to the lack of a license, but you can easily find them over at https://www.signalhound.com/support/downloads/sa44b-sa124b-downloads/ by yourself), but does not do anything useful yet.  Now to try test ouf the various methods in the class and make sure they are doing what I think they should be.  Eventually all this should be marked up in something visible a-la-doxygen
