React refactored to become shared library
- react.h and react.hpp files describes C and C++ public APIs,
  and react.cpp implements it
- now library is builded into libreact.so
- debian contains .deb build configurations
- react-bf.spec contains .rpm build configurations
- high_level and low_level examples added to show high_level API and
  direct low_level usage of library objects
Bindings for reverbrain projects removed, now reverbrain uses react public API
