Remarks:
Usage

     ./Intrepid_example_Drivers_Example_03.exe NX NY NZ verbose

        int NX              - num intervals in x direction (assumed box domain, 0,1)
        int NY              - num intervals in y direction (assumed box domain, 0,1)
        int NZ              - num intervals in z direction (assumed box domain, 0,1)
        verbose (optional)  - any character, indicates verbose output

     
Sample command line
 ./Intrepid_example_Drivers_Example_03NL.exe 10 10 10
