// MediaRouteProvider for DIAL sinks.
// DialMediaRouteProvider supports custom DIAL launch, which is a
// way for websites that uses Cast SDK to launch apps on DIAL devices.
// The life of a custom DIAL launch workflow is as follows:
// 1) The user initiates a custom DIAL launch by selecting a DIAL device
//    to cast to. This becomes a CreateRoute request to the
//    DialMediaRouteProvider.
// 2) The DialMediaRouteProvider sends NEW_SESSION / RECEIVER_ACTION messages to
//    the Cast SDK to inform of a new Cast session. In addition, a
//    CUSTOM_DIAL_LAUNCH request is sent to the Cast SDK.
// 3) The Cast SDK sends back a CUSTOM_DIAL_LAUNCH response. Depending on the
//    response, either the page have already handled the app launch, or the
//    DialMediaRouteProvider will initiate the app launch on the device.
// 4) Once the app is launched, the workflow is complete. The webpage will then
//    communicate with the app on the device via its own mechanism.
