 * ApexAssetTracker class
 * Intended to be a base class for asset classes that have named sub-assets.
 * - Allows their actors to easily get asset pointers
 * - Uses the NRP in an appropriate fashion
 *   - calls to checkResource(), createResource(), and getResource()
 *   - handles that tricky IOS asset double call mechanism
 * - Sub class must implement initializeAssetNameTable()
