taplint goes ObsTAP

[Mark Taylor]

Hi ObsTAP enthusiasts,

following encouragement from Pat, I have added ObsTAP validation features
to taplint, the STILTS-based TAP service validator tool.

As well as all the previous tests, for TAP services which claim
to implement ObsCoreDM, taplint now checks that all the required ObsCore
columns are in place, that all the column metadata for the required and 
optional columns matches what's written in the ObsCore spec,
and does a few additional tests on the data in those columns.

I won't make a public release of STILTS specially for this, but you can
find the pre-release jar file at:

   ftp://andromeda.star.bris.ac.uk/pub/star/stilts/pre/

Documentation (minus mention of the OBS stage, which is what does
the new ObsTAP stuff) can be found at:

   http://www.star.bristol.ac.uk/~mbt/stilts/sun256/taplint.html

Run it like this:

   java -jar stilts.jar tapurl=...

or if you just want ObsTAP tests:

   java -jar stilts.jar tapurl=... stages='TMS CAP OBS'

There may be errors in the validator; if you believe that it's claiming
an error where you don't think there is one (or vice versa) please let
me know.

Any questions etc you know where I live.

Mark
