[ADD] filter('controller.method') 

[ADD] filter('controller.method')  to determine which method that called by an endpoint URL.

I can use this to update my Web Title like:
- User Read
- User Search
- User Delete
- User Update
- User Create etc

If there is other method that I can use to determine which method that called by an endpoint URL, please let me know, so I can revert this revision. Thanks.
