[Math] Recursive Iterative approach on FFT

Hi !

I uploaded a patch for FastFourierTransformer.java on JIRA switching
from a iterative loop approach to a recursive iterative approach. I
had up to a 5x Performance Improvement on my test , Unit tests whwere
passed without any problems.

With regards,
