TODO:
*) Add 2d real optimized FFT
*) Make a better self-test program(s). Should report snr & timing for short,float,
or double.
*) Add real optimization for odd length FFTs
*) Add real optimization to the n-dimensional FFT
*) Add simple windowing function, e.g. Hamming : w(i)=.54-.46*cos(2pi*i/(n-1))
*) Make the fixed point scaling and bit shifts more easily configurable.
*) Document/revisit the input/output fft scaling
