Version 0.2.0

• Split install requirements into 3 files, which can be read either by pip
  or by the setup.py script.
  • requirements.txt is the usual file you install from
  • test-requirements.txt is a file intended for use when you are testing
    this repo.
  • dev-requirements.txt is the file you should install from if you are
    hacking in this repo.
• Added a custom Clusto-Mode header to change how the JSON data is
  presented back:
  • compact mode: is the default for API calls that return a list of items
    back to the requestor.
  • expanded mode: is the default for API calls that return a single item
    back to the requestor
• Added a by-names endpoint, it receives a list of parameters and will
  return back a list of items found
