Application
    star4ToFoam

Description
    Converts a Star-CD (v4) pro-STAR mesh into FOAM format.

Usage
    - star4ToFoam [OPTION] ccmMesh\n
      convert pro-STAR mesh to foam

    @param -ascii \n
    Write in ASCII format instead of binary

    @param -scale \<factor\>\n
    Specify an alternative geometry scaling factor.
    The default is @b 0.001 (scale @em [mm] to @em [m]).

    @param -solids \n
    Treat any solid cells present just like fluid cells.
    The default is to discard them.

Note
    - baffles are written as interfaces for later use
