What is the “SimulationParameters” element?

Simulation parameters refer to simulation engine settings that are used during simulation run-time.  These parameters are instructions for a simulation engine to take into account features such as simulation timestep (entered as a number of minutes which should be evenly divisible into 60, see timestep attribute), convergence limits (see ConvergenceLimits), and the version of the simulation engine (version attribute).  This element intends to maintain a record of the settings used to run a simulation, which may be important if gbxml stores simulation results, as a user may wish to know what settings and version of the simulation engine were used for analysis.
