 // Pointer to the main database connection used in the program.  This
 // pointer would normally be used for doing things as database lookups
 // for user login names and passwords, getting workstation settings, etc.
 // ---> IMPORTANT <---
 //
 //  For each database object created which uses this wxDb pointer
 //    connection to the database, when a CommitTrans() or RollBackTrans()
 //    will commit or rollback EVERY object which uses this wxDb pointer.
 //
 //    To allow each table object (those derived from wxDbTable) to be
 //    individually committed or rolled back, you MUST use a different
 //    instance of wxDb in the constructor of the table.  Doing so creates
 //  more overhead, and will use more database connections (some DBs have
 //    connection limits...), so use connections sparringly.
 //
 //  It is recommended that one "main" database connection be created for
 //  the entire program to use for READ-ONLY database accesses, but for each
 //  table object which will do a CommitTrans() or RollbackTrans() that a
 // new wxDb object be created and used for it.
