Util::Catalog (version $)

This class is useful for generating catalogs of files. Calling the "make" method will create a FITS output catalog with the standard format. The genral user does not need to worry about any of the other methods.

Certain catalog information is accumulated in the class data. This makes it more efficient to generate more than one catalog containing identical files. It also allows the "all_files" and "fits_files" methods to give lists of files in the union of all catalogs created so far.

Sub-classes may change the format of the catalog file by overriding some of the methods. The Util::HTMLcatalog class does this.
