Fast Fourier Transform algorithm inspired by the snippet http://fssnip.net/dC/title/fast-Fourier-transforms-FFT-. The original snippet was a beautiful and idiomatic implementation based on the definition of FFT. This version sacrifices idioms and elegance for performance. For data sets with 1024 samples this version seems to be about 100x faster and easier on the GC.

This rotates or shifts a list. Unlike http://www.fssnip.net/qY/title/Rotate-List, which runs exponentially, this runs at O(n). In case of overflow (i.e., shift index is larger than the size of the list) will run at most once more with the modulo. This is done to prevent using `List.length` prior to entering the function, as that would lead to a perf punishment of an extra O(n) on each invocation. For large lists, `shift largeList 1` would then get a big performance hit.

Returns the index of the first element in the sorted array that does not compare less than 'target'. The given method returns an option type to handling non matching cases. parameters: target - The value whose lower bound has to be found arr - sorted array beg - start index, usually zero en - end index, usually length of array minus one
