Base class for all plugin APIs. API Objects are the Java Objects that can be manipulated from Velocity or Groovy
scripts in XWiki documents. They wrap around a fully functional and privileged Plugin object, and forward safe calls
to that object.
Return the inner plugin object. This method is only for the plugin API's internal use, and should not be exposed
to scripting languages. It is an XWiki practice to expose all the functionality using an API, and allow access to
the internal objects only to users with Programming Rights.
