cql-java, version 0.3 - Changes

Changes between versions 0.2 and 0.3 of the cql-java distribution:

• Allow keywords to be used unquoted as search terms.
• Add support for the server choice relation, scr.
• Add support for prefix-mapping, as in

  	 >dc="http://dublincore.org/ dc.title=fish
  	

  and

  	 >"http://dublincore.org/ title=fish
  	

  The XCQL generated corresponds to Adam's suggested format rather than Rob's, not so much because I prefer it (although I do) as because it's what fell out when I just Coded What Comes Natur'ly. That may need to change, depending on the result of the ZNG list's deliberations.
• Fix the parser to normalise relation modifiers to lower case.
• Fix the CQLParser test harness not to emit an extraneous blank line at end of XCQL output.
• Fix CQLNode documentation to contain a link to YAZ's documentation of Prefix Query Format (PQF) rather than containing a rather unhelpful chunk of BNF.
• Change the test/regression Makefile so that make clean now does what make distclean used to do - the distinction between them is pointless.
• Fix a few typos in the documentation.
• Move the README file's old THINGS TO DO section to the end of the Changes file, the new Still to do section.
