/**********************************************************************
*  File:            attrList.H
*
*  Designer:        Willie Glover
*
*  Description:     attrList defines a list of attributes.  It is used 
*                   by legoRegion, opEdges, and legoOp.  The attrList 
*                   can contain attribute pointers (lc, live, and ms) 
*                   or it can contain non-ptr attributes (bb_id, freq, 
*                   etc.).
*
* 12/4/94 WAH: Added copy constructor.
* 9/5/97  WAH: Switched to enums in globals.H.
* 1/9/98  WAH: Fixed SetTableName to handle NULL.
* 1/27/98 WAH: Fixed destructor to delete tableName and intList.
