 *
 * Interface to the simulator, currently only used by control.cc.
 * The base class bx_simulator_interface_c, contains only virtual functions
 * and it defines the interface that control.cc is allowed to use.
 * In siminterface.cc, a class called bx_real_sim_c is defined with
 * bx_simulator_interface_c as its parent class.  Bx_real_sim_c 
 * implements each of the functions.  The separation into parent class
 * and child class leaves the possibility of making a different child
 * class that talks to the simulator in a different way (networking
 * for example).
