Description
    Convert a STARCD/PROSTAR (v4) mesh into OpenFOAM format.
 
Usage
    \b star4ToFoam [OPTION] prostarMesh
 
    Options:
      - \par -ascii
        Write in ASCII format instead of binary
 
      - \par -scale <factor>
        Specify an alternative geometry scaling factor.
        The default is \b 0.001 (scale \em [mm] to \em [m]).
 
      - \par -solids
        Treat any solid cells present just like fluid cells.
        The default is to discard them.
 
Note
    Baffles are written as interfaces for later use
