`route()` is the main method for defining routes within an application. For great detail on routes, check out: http://code.quirkey.com/sammy/doc/routes.html  This method also has aliases for each of the different verbs (eg. `get()`, `post()`, etc.)  ### Arguments  * `verb` A String in the set of ROUTE_VERBS or 'any'. 'any' will add routes for each of the ROUTE_VERBS. If only two arguments are passed, the first argument is the path, the second is the callback and the verb is assumed to be 'any'. * `path` A Regexp or a String representing the path to match to invoke this verb. * `callback` A Function that is called/evaluated whent the route is run see: `runRoute()`. It is also possible to pass a string as the callback, which is looked up as the name of a method on the application.
