- Bugfixes

LIBHYPPO:

Some heavy revisions of the SQL parser, now with some new approaches to the groups handling and a pair new operators

Some new crucial functions, such as the completely new inodes cache and advanced statements handling. Lots of bugfixes

Major bugfixes, and some adjustment in the way to supports a "GROUP BY" filesystem implementation.

Released the absolutly first implementation of Hyppocampus relational filesystem: it implement some fundamental function and a simple SQL parser.

In the CVS is accessible the concept prototype that is actually under development: this little application have the target to experiment algorithms and structures for the fisical disposition of metadata in the filesystem, using a simple binary file as a rappresentation of the hard disk. All contributions are welcome :-)
