+1.0 [IN PROGRESS]
+ - Support for CQL version 1.2 as described at
+ http://www.loc.gov/standards/sru/next-version.html
+ based on support for version 1.1 as described at
+ http://www.loc.gov/standards/sru/cql/
+ Since this is a significant leap forward, the version
+ numbering increases to the next major version.
+ - "Qualifiers" renamed as "indexes" throughout, to match what
+ is now universal CQL terminology.
+
+ PLEASE NOTE THE FOLLOWING INCOMPATIBLE API CHANGES
+ - The class UnknownQualifierException is replaced by
+ UnknownIndexException.
+ - The CQLTermNode method getQualifier() is replaced by
+ getIndex().
