Implement hook_help()

Please do not post screenshots of patches applying, that is a waste of time.

Also, the "assigned" field is for indicating you are actively working on something, not for indicating you worked on something; the maintainers will separately decide who should be given credit for their contributions on the issue.

Having reviewed the patch I think it needs work to better explain how to use the module. It might be more efficient to just load the contents of the README.md file and display it.

Hey, I made some changes in hook_help()! needs review

I appreciate the contribution but the readme text was borrowed from another module that was forked and modified and thus integrated as submodule to this one. So essentially, the readme is not currently even relevant to setup of this module and will be completely refactored. I'll leave this ticket open for tracking of this for the next release that will incorporate the actual changes needed ASAP. Thanks.
