Select which fields to process

Now got the ability to define which fields to calculate stopwords from. This to not add noise comming from fields where words in general have a lower stopwordiness. Client and tests updated too.

Now a library + client

index.js is now the library part that can be used from any script. Created a small commander-based console client that will take some input.

Acually ready for use

Both stopwords.json and stopwords-calculation.json are now written. The first is a subset of the last, only containing the words in an array. Cut-of needs to be done manually, since it contains all found words, not just the top [n] words.

First working version

Rudimentary calculation in place. Still need to have a stopword-generator to fit the module stopword.
