Kwabena W. Agyeman 45fdcc973e Add FFT Code and Phase Correlation Code
The heart of the 1D FFT works. I tested this on the PC. However, 2D FFTs
may have issues and the phase correlation algorithm does not generate
the expected results. That said, most of the work is done. Stuff just
needs to be deubgged.

The FFT lib is designed to handle up to 1024 point real FFTs and 512
complex FFTs. As for 2D FFTs, we can do up to 64x64 pixels. After which,
we don't have enough RAM to handle them because they use up about 128KB
each.

Things to do... the 2D FFT needs to be verified. So, we need to run an
image through it and then back again to verify that there are no
problems. Then we need to compare the 2D FFT output with another 2D FFT
algorithm on the PC...

Once the FFTs are known to be good we then need to make sure the phase
corelation algorithm outs the correct results. We need to test that with
multiple shifted images, etc.
