/// Creates an ARCore Cloud Anchor at the location the user tapped and passed into it. This function can be used to set the world origin or just a normal cloud anchor.

/// <param name="_anchorObjectPrefab">The ASL object you want to have located at the cloud anchor. If you don't want any object to be located at the cloud anchor, you can pass in null.
/// Doing so will create an empty gameobject - thus making it invisible to users</param>
/// <param name="_myPostCreateCloudAnchorFunction">This is the function you want to call after a cloud anchor has successfully been created. Only the user that called this function
/// will execute this function - it is not sent to other users. This is a good way to move or create objects after a cloud anchor has been created.</param>
/// <param name="_waitForAllUsersToResolve">This determines if users should wait to setup (and if they are the caller of this function, to execute the _myPostCreateCloudAnchorFunction)
/// the cloud anchor once they receive and find it, or if they should wait for all users to receive and find it first before executing anything. The default is to wait for all users
/// and is the suggested value as not waiting as the potential to cause synchronization problems.</param>

/// so right away in your app and as the first (if you have more than 1) cloud anchor created. You should never set the world origin more than once.</param>
