/**  A template class for auto_ptr-like functionality
 * Uses a method other than delete to clean up the stored object.
 * It also doesn't have any of auto_ptr's ownership concepts.
 *
 * If the deleter function doesn't take pointers of the template's type it may need to be
 * cast to get rid of compiler warnings. Often the pointer type taken by the deleter will
 * be 'void *'.
 *
 * Example: xmlSmartPtr<char> rowDel( rowData, (xmlSmartPtr<char>::deleter)xmlFree );
