Refactor function names to reflect general nature of calls
Refactor function names to reflect general nature of calls

  -- Several functions have been changed to reflect that they
     will work on not only single words, but ngrams more generally.
     These are mostly internal functions that don't affect the CLI
     tool's functionality directly.

     Affected functions are countNGram, getNGramsFreqs, and
     ngramCountProfile, the names of which used to imply that
     these functions were only good for lexeme level profiling
