Added a new header of vectorial inline functions for Neon and Helium.
This header is used in the implementation of some functions.
Corrected used of float (float functions rather than double ones).
Added new tests for cfft.
Improved error handling when not enough memory allocated in testmain.cpp
Corrected arm_math.h (replaced inline by preprocessor definition).
Added example debug script to read pattern and output of tests using
scipy.
