To Do (16th June 2004)
---------------------
* Introduce support for quality flags with Astro::Catalog::Item::Quality
object.
* Fix things so all "values" are represented by the new Number::Uncertainty
object and can have associated errors. Currently only flux values use the
new Number::Uncertainty class.
* Add output support for FITS binary tables.
* Support the VOTable V1.1 standard.
* Fix Astro::Catalog::Query::CMC module to correctly parse the CMC TST files,
currently support is somewhat broken. The module itself may no longer work
at all under the new V4 API.
* Add writing support for TST files to Astro::Catalog::IO::TST
* Fix Astro::Catalog::Query::SkyCat and Astro::Catalog::Query::Vizier to
be truely generic (or at least work in more cases out of the box).
* Change Astro::Catalog::Query::Vizier to use VOTables for easier parsing?
* Add further catalogue query classes?
