Determine what a particular file is

Synopsis
whatis(file, dir)

Description
Analyzes the file characteristics to determine what it contains:

• Tables are easily recognized and the type (e.g. Measurement Set, Image, Calibration) determined,
• Directories, Postscript, Graphics, Glish, and FITS files are recognized,
• Other files may give mixed results, either showing up as Regular File or ascii.

Note that symlinks are normally resolved, so only if the file linked to does not exist, the type will be 'symbolic link'..
