Updated spelling code to allow for other string distance measures to be used.

Created StringDistance interface.
Modified existing Levenshtein distance measure to implement interface (and renamed class).
Verified that change to Levenshtein distance didn't impact runtime performance.
Implemented Jaro/Winkler distance metric
Modified SpellChecker to take distacne measure as in constructor or in set method and to use
interface when calling.
