/// <summary>
/// This is a helper function that verifies that the player's move wasn't made
/// too quickly following their previous move, according to the rules of the game.
/// If the move is valid, then it updates the player's statistics and profile data.
/// This function is called from the "UpdatePlayerMove" handler above and also is
/// triggered by the "RoomEventRaised" Photon room event in the Webhook handler
/// below.
///
/// For this example, the script defines the cooldown period (playerMoveCooldownInSeconds)
/// as 15 seconds.A recommended approach for values like this would be to create them in Title
/// Data, so that they can be queries in the script with a call to GetTitleData
/// (https://api.playfab.com/Documentation/Server/method/GetTitleData). This would allow you to
/// make adjustments to these values over time, without having to edit, test, and roll out an
/// updated script.
