 * specified timeout has elapsed, or the SDLAlert is preempted</li>
 * <li>An SDLAlert will preempt (abort) any SmartDeviceLink Operation that is in-progress,
 * except an already-in-progress SDLAlert</li>
 * <li>An SDLAlert cannot be preempted by any SmartDeviceLink Operation</li>
 * <li>An SDLAlert can be preempted by a user action (button push)</li>
 * <li>An SDLAlert will fail if it is issued while another SDLAlert is in progress</li>
 * <li>Although each Alert parameter is optional, in fact each SDLAlert request
 * must supply at least one of the following parameters:<br/>
