Controllers module for the ABingo Camping Plugin. The module will be plugged in to the main app controllers module using:

       - extend to add class methods to the app controllers module
      -  include_abingo_controllers to dynamically plugin the ABingo and Helpers modules inside each controller class
              (this is why the call must be the last statement in the controllers module)

Example:

 module CampingABingoTest::Controllers
              extend ABingoCampingPlugin::Controllers

              # ...

              include_abingo_controllers
 end
