Add #include <time.h>

Add return 1 to saveBRep

Changed the return type of GetOBB from SOrientedBoundingBox* to SOrientedBoundingBox

Bugfixes.

Added a sort of the eigenvalues and print functions

reorganized the API examples + show how you can build a new GUI using
the lib

Bugfixes. Added notion about possible torsion of generators of homology
groups.

Bugfixes around the place.

Changed GMSH_LIBS order in configure.in in order to make linker work with
homology computation plugin under linux.

Added more message console info about homology computation.

Added "#if defined(HAVE_KBIPACK)" preprocessor directives to only enable
homology plugin & compile the code when kbipack & gmp library is avaible.

Added Geo/Homology.h and Geo/Homology.cpp as mid-interface for homology
computation (the role of utils/misc/celldriver.cpp so far). From there on
it's easy to either make plugin interface or parser interface, or both.

Made Homology Computation plugin usable.

The IO & graphics for post-processing views of the results of the homology
computation are crude at the moment: it saves the results to a separate
.msh file and reads them back by merging that to the current Gmsh session
(it uses File->Merge method).
