commit 4a998817a8ca56749d73e5aebeb74e57c130e3c2
Author: Chris Wacek <cwacek@xxxxxxxxxxxxxxxxx>
Date:   Tue Jan 15 15:41:56 2013 -0500

    Provided default arguments for all parameters.
    
    Now a blank request will no longer fail with a server
    error and will instead return a default set of data.
