This:

https://github.com/owen2345/camaleon_oauth/blob/master/config/initializers/doorkeeper.rb#L1

makes methods like current_user available in the global scope.

However, current_user invokes cama_calc_api_current_user which invokes doorkeeper_token. doorkeeper_token is not available in the global scope, hence current_user fails.

Furthermore, cama_current_user has a cache for the current user value - @cama_current_user. This is an instance variable which again is not accessible from the global scope.

Instead of putting methods into the global scope, specific classes or modules should include CamaleonCms::SessionHelper etc.

I installed this gem and ran rails db:migrate, and I enabled the plugin in /admin/plugins. However, the /admin/register screen is the same as before (no oauth options). Additionally, the documentation link in /admin/plugins doesn't work. Are there additional steps to install?

Rails 5.1.4
Ruby 2.4.2
Camaleon git version

This repo does not have any release tags, would be good to have them.
