/**
 * This method should be used to execute a {@link PermissionsResultAction} for the array
 * of permissions passed to this method. This method will request the permissions if
 * they need to be requested (i.e. we don't have permission yet) and will add the
 * PermissionsResultAction to the queue to be notified of permissions being granted or
 * denied. In the case of pre-Android Marshmallow, permissions will be granted immediately.
 * The Fragment variable is used, but if {@link Fragment#getActivity()} returns null, this method
 * will fail to work as the activity reference is necessary to check for permissions.
 *
 * @param fragment    the fragment necessary to request the permissions.
 * @param permissions the list of permissions to request for the {@link PermissionsResultAction}.
 * @param action      the PermissionsResultAction to notify when the permissions are granted or denied.
