Detailed Description

Manages runtime construction of Physics objects.

This will parse the input file for the requested Physics and manage their construction. Actual construction of the Physics object is delegated to PhysicsFactoryBase subclasses. The PhysicsBuilder merely manages tasks around them as needed. To add a new Physics, the user should instantiate an appropriate PhysicsFactoryBase subclass.
