abbrev(words, pattern = nil)

Given a set of strings, calculate the set of unambiguous abbreviations for those strings, and return a hash where the keys are all the possible abbreviations and the values are the full strings. Thus, given input of "car" and "cone", the keys pointing to "car" would be "ca" and "car", while those pointing to "cone" would be "co", "con", and "cone".

The optional pattern parameter is a pattern or a string. Only those input strings matching the pattern, or begging the string, are considered for inclusion in the output hash
