Set up the runtime controls

To set up the runtime controls, an instance of the class SPARK::TRuntimeControls should be instantiated with the name of the *.run file passed to the constructor along with a name for the set of controls (used mostly for debugging purposes in case you use multiple SPARK::TRuntimeControls objects in the same run).

This class parses the *.run text file and generates an internal representation of the runtime control parameters that can then be queried by the other SPARK classes.

    SPARK::TRuntimeControls RuntimeControls( 
           "Default SPARK driver",  // name of controls set
           RunFileName              // *.run file name
    );
