The compute graph hierarchy (Python and C++) has been modified.
It will break the code using the CG and the include and import will
have to be modified.
New function prepareForRunning is needed in CG nodes even if not used in
static mode. Without this function, code using compute graph won't build.
Corrected issues with arm_fir_decimate and arm_fir_interpolate
Corrected issues with real FFTs in the wrapper
Added a customization option for the FIFO class in compute graph.
Added Python tests for the corrected functions.
