Updated content to conform to experiment template

Please do not merge!  This content is awaiting review/addition by Ryan Coleman. 

Before alterations, this content was the module author-determined
description of and instructions for use of the module.
As part of an effort on the Forge team to standardize formatting and
encourage quality module documentation, templates were created for
user-experience testing. This module was chosen due to its popularity
and was changed to fit one of the template styles the Forge is testing.
I pulled in content from both READMEs on GitHub, the Module of the Week
blog post, and Nick Lewis's blog post about the module to ensure
complete coverage. Standard headings were added (Module Description,
Usage, Implementation, etc.), existent and pulled-in content was moved under
its appropriate heading and edited for tone/flow/clarity, and
formatting was done to adhere to
template standards.
