/* Definition of the generic obj class module.
 *
 * This module relies heavily on preprocessor macros in order to
 * provide fast execution time AND ease of use.
 *
 * Each object that uses this base class MUST provide a constructor with
 * the following interface:
 *
 * Destruct(pThis);
 *
 * A constructor is not necessary (except for some features, e.g. de-serialization).
 * If it is provided, it is a three-part constructor (to handle all cases with a
 * generic interface):
 *
 * Construct(&pThis);
 * SetProperty(pThis, property_t *);
 * ConstructFinalize(pThis);
 *
 * SetProperty() and ConstructFinalize() may also be called on an object
 * instance which has been Construct()'ed outside of this module.
 *
 * pThis always references to a pointer of the object.
