There is a group of routes called the RouteCollection, which consists of registered routes in the application.The RegisterRoutes method records the
routes in this collection. A route defines a URL pattern and a handler to use if the request matches the pattern. The first parameter to the
MapRoute method is the name of the route. The second parameter will be the pattern to which the URL matches. The third parameter might be the
default values for the placeholders if they are not determined.
