Fuzzy Hash

This is useful when you want to have a lookup table that can either contain strings or regexes. For instance, you might want a catch all for certain regexes that perform a certain logic.

>> hash = FuzzyHash.new
>> hash[/^\d+$/] = 'number'
>> hash[/.*/] = 'something'
>> hash['chunky'] = 'bacon'
>> hash['foo'] = 'vader'

>> hash['foo']
<< 'vader'
>> hash['food']
<< 'something'
>> hash['123']
<< 'number'
