Derek Kozel 6622a947ae cmake: Refactored code structure into library with examples 
The project now supplies the m17cxx library in a form usable by third
party applications. An example standalone CMake based app is included to
as a reference or starting place. The modulation and demodulation
utilities are included as apps.
