This class provides access to routines to allow users to read and write FITS files.

Description of the Package
This FITS package attempts to make using FITS files easy, but does not do exhaustive error checking. Users should not assume that just because a FITS file can be read and written that it is necessarily legal FITS.
- The Fits class provides capabilities to read and write data at the HDU level, and to add and delete HDU's from the current Fits object. A large number of constructors are provided which allow users to associate the Fits object with some form of external data. This external data may be in a compressed format.
- The HDU class is a factory class which is used to create HDUs. HDU's can be of a number of types derived from the abstract class BasicHDU. The hierarchy of HDUs is:
  - BasicHDU
    - ImageHDU
    - RandomGroupsHDU
    - TableHDU
      
      BinaryTableHDU
      AsciiTableHDU
- The Header class provides many functions to add, delete and read header keywords in a variety of formats.
- The HeaderCard class provides access to the structure of a FITS header card.
- The Data class is an abstract class which provides the basic methods for reading and writing FITS data. Users will likely only be interested in the getData method which returns that actual FITS data.
- The TableHDU class provides a large number of methods to access and modify information in tables.
- The Column class combines the Header information and Data corresponding to a given column.
