Mark Pizzolato 110ded6904 FRONTPANEL: sim_frontpanel API version 3 release 
Adds:
1) Simulator side execution of register update activities at an interval
    specified in usecs.  Rates in excess of 1000Hz should be achievable
    for locally connected frontpanel applications.
2) New API for simulators to describe the register state available in
    the simulator.  If all of a the state which is potentially interesting
    to front panel applications is always present in the variables
    described by simh REG structures, then frontpanel API access to
    that data can be more efficiently provided.

This module demonstrates the use of the interface between a front panel
application and a simh simulator. Facilities provide ways to gather
information from and to observe and control the state of a simulator.
