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 the original README on GitHub and the Module
of the Week blog post. 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, links to outside documentation were updated, and
basic formatting was done to adhere to template standards.
Fixed typos, rewording and typsetting per feedback

Updated spelling errors, typsetting issues and some wording suggestions
based on module author feedback
