//File:        spaceSR.h
//
//Class:       DtSpaceEntityStateRepository
//
//Description: This repository holds all information that is common to all the
//forms of space entities within the system.  It contains a pointer
//to the space entity parameters, and provides accessors and mutators
//for all parameter values.  In this example, we add a single new parameter,
//myCurrentHullTemperature, representing the current hull temperature of this
//(e.g. such as during reentry).  Any future controller and actuator components
//we build to simulate the entity's behavior can view or set this new parameter as necessary.
