Namespace or prefixes or singleton

[jrastaban]

I'm super excited about what this plugin is enabling content creators to do. Reviewed the code and it seems to work well. I'm just going to submit some issues around best practices for when this moves into the clean up tech debt phase.

To make sure common function names don't conflict with other plugins it is recommended to take steps to make yours unique. It use to be best practice was to prefix the plugin name to all functions but now that the WP minimum supported PHP version has been bumped people have been moving to using name spaces.
