0.25
    - added a select_parser method so that you can specify
      the sax parser to use (defaulted in the past to pureperl
      which is way too slow)
    - added dependency for XML::LibXML (since we use their SAX
      parser now by default);
    - added a verbose param to Ontology/OWL/Lite.pm that triggers 
      a call to debug() in init()
    - added a 'do_impl' param to Ontology/OWL/Lite.pm that triggers
      the ->implementations() part of Lite.pm. Look at owllite2perl.pl
      for how to set the parameter.
    - DBD::mysql is now a dependency iff mysql is accessible on
      the users machine.
      
0.23/0.24
    - added a check in issue_query that checks to see whether 
      the $query was parsed correctly into a ODO::Query::RDQL
      in ODO::Graph::Storage::Memory.
    - added more text for warning of missing properties.
    - bug fix: subClassOf was being added as a restriction and
      not to inheritance 
0.22
    - when parsing owl files, import statements are parsed out,
      but not traversed. They are returned to the user though.
      NOTE: if you use prior versions of ODO::Parser::XML, your
      code may break as statements and imports are returned after
      calling parse. owllite2perl illustrates this.
      
     owllite2perl needs to be updated to produce actual modules, etc.
     This will hopefully be accomplished next release. In SADI::SADI,
     a code generator that is based on this module exists. However,
     it uses RDF::Core to serialize the RDF.
     
     - Fixed the RDF code generator. It now produces valid Perl code.
     - Went through ODO::Ontology::RDFS code and fixed how it processed
       statements. Basically, I made sure that ISA/inheritance dont contain
       any undef keys/values. Then i updated the templates so that my updates
       to ODO::Ontology::RDFS.pm were taken into account.
     - Updated the test scripts to take into account that parse
       now returns statements and imports
     - updated the example scripts to take into account the above.
     - updated the makefile to add DBD-mysql (eventhough, the db
       side of ODO/Pluto doesnt work).
     - added VERSION info for each file that reflects the cvs revision to aide
       in diff'ing the files.

0.21
    - Added missing methods that were referred to in Lite.pm
    - Updated the OWL SAX parser so that entities prefixed by #
      now have theh base xmlns appended to it
    - The owl2perl example script still doesnt work 100%, but
      a script in SADI (sadi-generate-datatypes) does something
      similar to this script and uses ODO to do it.
    - Cleaned up the Makefile.PL script (uses Module::Install now)
