Simplification of matching-type logic adapters

This is a cool internal change that occurred for this release. By pulling several statement comparison methods out into their own module, much of the code for several matching style logic adapters became nearly identical. This made it possible to reduce a large amount of repeated code.

In a future release, all of the matching style logic adapers (ClosestMatch, ClosestMeaning, SentimentAnalysis, ApproximateSentenceMatch) will be replaced by a single MatchingAdapter class that will allow the comparison function to be set as a parameter.

• Modify synset_distance comparison function [https://github.com//pull/385]
• The comparison function now returns a percent so it can be easily compared to other comparison methods.
• This change allowed the codebase for the closest match adapter and the closest meaning adapter to be combined.
• Move sentiment matching to it's own function [https://github.com//pull/386]
• Don't override get method on ApproximateSentenceMatchAdapter [https://github.com//pull/387]
• Add check for if logic adapter string parameters need to be imported [https://github.com//pull/395]
