          expand to all defined if fields if 'default_field' is not

0.09    03 March 2010

        * POD fixes.

0.10    14 March 2010

        * add range support to SQL dialect.

        * fix bug with stringification of SWISH dialect and compound negatives.
        * fix bug in Dialect->add_sub_clause()

0.14    30 April 2010
        * add !: operator support to Parser
        * fix Dialect->add_*_clause methods to properly add () around 
          the existing and new clauses, to get logical groupings correct.
        * add stringify() method to Clause
        * add clear_error() method to Parser
        * fix bug where expanded alias_for field array was not passing
          through quote or proximity values.

0.15    06 May 2010
        * add sanity check in Parser so that stringify() is tested. If a parsed
          query cannot be re-parsed after stringify() then the stringify() method
          is broken.

0.16    08 May 2010
        * fix uninitialized value warning in Clause->stringify

       
0.17    22 June 2010
        * add field=(a..b) regex case to Parser so that the Clause is not stored
          as a child of a () Clause.
        * simplify the preservation of () clauses.

0.18    25 July 2010
        * add Parser->term_expander feature
        * refactor Dialect->tree() and ->translate_to() methods to avoid dependency
          on Clone module. This also fixes a segfault when calling those methods
          on objects that contain blessed C pointers, like Search::Query::Dialect::KSx.
