Create a new instance of the push matched template router.

This constructor should be used in case a path matching has been performed on both a resource and method paths
(in case of sub-resource methods and locators).

Params:
resourceTemplate – resource URI template that should be pushed.
methodTemplate –   (sub-resource) method or locator URI template that should be pushed./**
