Synopsis:
       Wrapper script for plt2cub_dens. Call plt2cub_dens to obtain a 
       .cub density file from a .plt density file with a dummy H atom
       in the origin.
       Then replace the dummy H atom with a molecule in xyz format. 
Usage:
       plt2cub pltfile {xyzfile}

       default for xyzfile is coord.xyz. Cubefile will be named after the
       pltfile.
