Class Imtype

Class which determines the format of the file, how to access the
SCI data array, and if available, any DQ array as well.  The syntax
for accessing the data will then be kept as attributes for use by
other tasks/classes.

Parameters:
    filename    -   name of file to be examined
    handle      -   PyFITS-style file handle for image
    dqsuffix    -   suffix for DQ array for non-MEF files

If 'dqsuffix' is not provided and the file is GEIS formatted,
then this class will search for a '.c1h' extension by default,
and return None if not found.
