 *
 * Project:  OGR
 * Purpose:  Implements OGRAVCLayer class.  This is the base class for E00
 *           and binary coverage layer implementations.  It provides some base
 *           layer operations, and methods for transforming between OGR
 *           features, and the in memory structures of the AVC library.
