// 5/13/01:  Converted comments to javadoc format.
// 11/16/99: changes to support new noise calculations
// 9/18/98:  class cascade is now a subclass of data_ptr_nport.
// 9/17/98:  converted algorithm to use tree structure for
//           storing intermediate stages of connections.
//           circuit::recalc() no longer recreates temporary
//           connection class devices.
// 8/21/98:  added circuit::pop_port(); added class cascade
// 8/19/98:  added a local temperature Temp
