	A variation of both the SoundEx and PhonetEx algorithms. Double Metaphone performs 2 different PhonetEx-style transformations. It creates two PhonetEx-like strings (primary and alternate) for both strings based on multiple phonetic variations which originated from other languages. Unlike Soundex and Phonetex, the Metaphones are generated during the comparison algorithm.		:A variation of both the SoundEx and PhonetEx algorithms.
