[Roadmap] Add Boilerplate Plugin Using WPO Framework

[theperfectwill]

Is your feature request related to a problem? Please describe.

No.

Describe the solution you'd like

A (mostly) ready to code type of template plugin for devs to get started with WPOnion. See "Additional Context".

Describe alternatives you've considered

A reference of a kind of sort of this idea can be found at: https://github.com/WPBP/WordPress-Plugin-Boilerplate-Powered

• There are some library references in the above plugin that seem useful as well, maybe to consider adding to the core of WPO (tweaked as needed), but we also have already some of these library concepts in WPO (so no need for those ones).

Additional context

To make this boilerplate one in the same for the demo install for users to demo, and one in the same for the WPOnion Docs.

So building the base of the plugin, along with the docs and walkthroughs, and then making that plugin the demo in the demo site.
