	Defines a collection of routes for given controller.

	RouteCollection: class RouteCollection
		
		###
		Constructs route collection instance.

		Arguments:

			appRoutes - hash of routes, for example 

				"route-name": url: "route-url", action: "controllerAction"
				"route-name-2": 
					url: "route-url-2", 
					action: "controllerAction2",

				controller: @_getController()
			@router = new Router

		###
		Navigates to given url.

		navigate: (url) ->
			@router.navigate url, trigger: true

		Arguments:

			routes - array of RouteCollection instances
		###
		constructor: (@routes) ->
		
		###
		Starts routing mechanism (which watches current URL for hash changes).
		###
		start: ->
			Backbone.history.start()

		###
		Launches appropriate controller action using given route and parameters.
