Updated content to conform to README best practices template

Before alterations, this content was the module author-determined description of and instructions for use of the module.

As part of a joint Forge/Docs team effort to standardize formatting and encourage quality module documentation, a best practices README template was created via internal and external user testing. That template was then applied to this module. 

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. A table of contents was added for navigability, standard headings were added (Overview, Module Description, Setup, Usage, Implementation, etc.) to organize content, existent and pulled-in content was moved under its appropriate heading and edited for tone/flow/clarity, and basic formatting was done to adhere to template standards.
