* This class represents a parsed UDP. This is a much simpler object
* then a module or macromodule.
* - all ports are scaler,
* - pin 0 (the first port) is always output,
* and the remaining pins are input.
* Thus, the ports can be represented as an ordered list of pin names.
* If the output port is declared as a register in the Verilog source,
* then this is a sequential UDP and the sequential flag is set to true.
* Each entry in the state table is given as a string with the same
* number of characters as inputs. If the UDP is sequential, a
* character is also included at the end of the string to represent
* the current output.
* If the UDP is sequential, the "initial" member is taken to be the
* intial value assigned in the source, or 'x' if none is given.

* Get rid of the STL vector template.
* Revision 1.2 1998/12/01 00:42:13 steve
* Elaborate UDP devices,
* Support UDP type attributes, and
* pass those attributes to nodes that
* are instantiated by elaboration,
* Put modules into a map instead of
* a simple list.
* Revision 1.1 1998/11/25 02:35:53 steve
