    Checkstyle configurartion that checks the Google coding conventions from:

    -  Google Java Style
       https://google-styleguide.googlecode.com/svn-history/r130/trunk/javaguide.html

    Checkstyle is very configurable. Be sure to read the documentation at
    http://checkstyle.sf.net (or in your downloaded distribution).

    Most Checks are configurable, be sure to consult the documentation.

    To completely disable a check, just comment it out or delete it from the file.
