Dispatches to alternate controller methods based on HTTP method

Multiple keyword arguments should be passed, with the keyword corresponding to the HTTP method to dispatch on (DELETE, POST, GET, etc.) and the value being the function to call. The value should be a string indicating the name of the function to dispatch to.

Example:

class SomeController(BaseController):
    @pylons.rest.dispatch_on(POST='create_comment')
    def comment(self):
        # Do something with the comment
    def create_comment(self, id):
        # Do something if its a post to comment
