/**
* Easily register a RegExp, string, or function with a caching
* strategy to a singleton Router instance.
*
* This method will generate a Route for you if needed and
* call [Router.registerRoute()]{@link
* workbox.routing.Router#registerRoute}.
*
* @param {
* RegExp|
* string|
* workbox.routing.Route~matchCallback|
* workbox.routing.Route
* } capture
* If the capture param is a `Route`, all other arguments will be ignored.
* @param {workbox.routing.Route~handlerCallback} handler A callback
* function that returns a Promise resulting in a Response.
* @param {string} [method='GET'] The HTTP method to match the Route
* against.
* @return {workbox.routing.Route} The generated `Route`(Useful for
* unregistering).
