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.
