[ddlm-group] testers for vcif 3

Testers are needed for vcif_3, an upgrade to vcif (a mode of calling
CBFlib's cif2cbf) that validates CIFs against dictionaries.  E. Zlateva
(elitty@gmail.com) has coupled CBFlib to James Hester's dREL parser,
so that 2007 and 2008 DDLm-dictionary-based CIFs can be tested in
addition to DDL1 and DDL2.

    The kit is available from sourceforge as

    http://downloads.sf.net/vcif/vcif_3_9Dec09.tar.gz

This kit includes a matching CBFlib kit.  The sourceforge cbflib
project svn repository has the same version of CBFlib in the
CBFlib_bleeding_edge module.

    The kit assumes a working python, and has been tested against
python 2.5 and python 2.6 under Mac OS X and slackware linux with a
2.6 kernel.  In addition to python itself, you will need

http://downloads.sf.net/cbflib/numpy-1.4.0rc1.tar.gz
http://downloads.sf.net/cbflib/ply-3.2_7Dec09.tar.gz
http://downloads.sf.net/cbflib/dREL-ply-0.5_9Dec09.tar.gz
http://downloads.sf.net/cbflib/PyCifRW-3.3_6Dec09.tar.gz

Note that the last 2 are modified versions of James Hester's kits
of similar names.

This is an interim version for trial while we are waiting for the
CIF2/DDLm spec to be completed.  In view of the need for possibly extensive
changes for the new spec, internal communications between CBFlib
and the python-based dREL parse are via files, rather than pipes,
and a great deal of debug output is enabled.

Many thanks to James Hester for his parser and helping us to get
the interface working.

Comments, corrections and suggestions would be appreciated.
