0.4.1

Changes:

• Added key classes to the top-level textacy imports, for convenience:
  • textacy.text_stats.TextStats => textacy.TextStats
  • textacy.vsm.Vectorizer => textacy.Vectorizer
  • textacy.tm.TopicModel => textacy.TopicModel
• Added tests for textacy.Doc and updated the README's usage example

Bugfixes:

• Added explicit encoding when opening Wikipedia database files in text mode to
  resolve an issue when doing so without encoding on Windows (PR #118)
• Fixed keyterms.most_discriminating_terms to use the vsm.Vectorizer class
  rather than the vsm.doc_term_matrix function that it replaced (PR #120)
• Fixed mishandling of a couple optional args in Doc.to_terms_list
