        Open an input file for reading.

        The input file can be of 2 different forms:
          - the usual Class Data Format (.30m or other produced by several tele-
            scopes, and by Class itself),
          - a  VLM  (Velocity-Position-Position) cube in the Gildas Data Format.
            LMV cubes must be transposed first to VLM before use.
        The usual Class commands (FIND, GET, etc)  work  transparently  on  both
        kind of files.
