Match route to request

[mytuny]

Problem:

Defined route:

WP_Route::get('flights', 'callbackFn');

Any of the following request URIs will match with the above route definition and 'callbackFn' get fired: "/flight", "/anytext", "/tttttttt", "eeee" ...etc

Fix:

An additional utility method called "matchRouteToRequest" has been added. Then, we add a filter inside the 'handler' to filter-out the routes with a pattern that do not match the requested URI.
