Description
    This utility sets up a multi-region case using template files for
    material properties, field and system files.

    The utility reads constant/materialProperties to create a
    regionProperties file and to create region directories containing
    required files within the 0, system and constant directories. The
    materialProperties file contains mesh region names with an
    associated physical region type and a material:

    bottomAir
    {
        type            fluid;
        material        air;
    }

    The case must contain a directory called templates, with e.g. the
    following directories and files:
    + 0
      + fluid: p, p_rgh, U, T, k, omega, epsilon, nut, alphat
      + solid: p, T
    + system
      + fluid: fvSchemes, fvSolution, decomposeParDict
      + solid: fvSchemes, fvSolution, decomposeParDict
    + constant
      + fluid: g
      + solid
    + materials
      + air: radiationProperties, thermophysicalProperties, turbulenceProperties
      + aluminium: radiationProperties, thermophysicalProperties
      + ...
