cql-java, version 0.4 - Changes

Changes between versions 0.3 and 0.4 of the cql-java distribution:

• Add support for the new phonetic relation modifier, including its mapping in etc/pqf.properties.
• Make prefix-maps bind loosely, so that >dc=x a and b applies the dc=x binding to both the a and b sub-queries.
• Change the XCQL output to include the nasty (but official) <leftOperand> and <rightOperand> wrapper elements.
• Change the XCQL output to use the nasty (but official) rendition of prefix-mapping: a <prefixes> element, containing one of more <prefix>es may appear at the top of either a <searchClause> or a <triple>.
• Include test/regression/xmlpp.pl in the distribution: this XML canonicaliser may now be used for testing whether a CQL compiler produces equivalent XCQL to what's in the regression test, rather than requiring byte-identical output.
• Include the reference XCQL output in the distribution, for the regression test suite to run against.
• Change build process so that javadoc documentation is built by make in the docs directory. There's now a top-level Makefile that builds the source, runs the test suite and creates the documentation.
• Write javadoc comments for CQLRelation and ModifierSet.
• Other improvements to javadoc comments (e.g. describe the config parameter to the toPQF() method.)
• Sort out the licence: I've settled on the LGPL.
• Remove the redundant and misleading etc/Grammar file.
• Fix up various Maintenance Agency web addresses that have moved in the great ZING-release shake-up.
