class	FloatTableFNTStrategy Fast Number Theoretic Transform strategy that uses lookup tables for powers of n:th root of unity and permutation indexes.
class	IntTableFNTStrategy Fast Number Theoretic Transform strategy that uses lookup tables for powers of n:th root of unity and permutation indexes.
class	LongTableFNTStrategy Fast Number Theoretic Transform strategy that uses lookup tables for powers of n:th root of unity and permutation indexes.
class	SixStepFNTStrategy Fast Number Theoretic Transform that uses a "six-step" algorithm to calculate a long transform more efficiently on cache-based memory architectures.
