MAA version 0.2.0 moves to a standard C API

* Removed all C++ code and renamed all .cxx extensions to .c
* All functions are renamed to maa_ and modules are for example called maa_pwm
* Cmake can now 'make doc' using a Doxyfile.in to create documentation
* examples/ have been updated but swig generated API is untested
