FLASH4 complete API

   These are the runtime parameters used by the basic Grid unit.
   Your specific implementation (Paramesh, UG) WILL have more 
   runtime parameters particular to that unit. Since parameters
   inheritance is cumulative, all of the ones described here will
   be included by all the specific implementations.

   To see the default parameter values and all the runtime parameters
   specific to your simulation check the "setup_params" file in your
   object directory.
   You might have overwritten these values with the flash.par values
   for your specific run.  

    bndPriorityOne [INTEGER]
        indicates which axis, x,y,z has priority in guardcell filling at
        the physical boundaries.
        Defines priority of x direction boundary filling, can be 1,2 or 3
    bndPriorityThree [INTEGER]
        defines priority of z direction boundary filling, can be 1,2 or 3
    bndPriorityTwo [INTEGER]
        defines priority of y direction boundary filling, can be 1,2 or 3
    convertToConsvdForMeshCalls [BOOLEAN]
        indicates if vars are converted from primitive (i.e., velocity) to conservative 
        (i.e., momentum) before Grid functions that interpolate data are invoked.
        With PARAMESH3 or later, convertToConsvdInMeshInterp should be used instead.
