Release 1.0

  - The major chage to this release is support for .Z compressed images.
    This is implemented by using the uncompress command which must
    be in the user's execution path. 
  - There is much more dynamic checking of the magic number of inputs
    to determine whether the input to the FITS constructor is compressed
    or not, and if compressed what the compression type is.
    This can still be confused but in many cases it will get the
    compression right regardless of what the user specifies.
    Future versions may completely ignore the user specified compression
    flag.
