* unitTesting/test_signalcast.cpp.

Added an example of caster construction for type vector (dummy cast, similar to the default one, just for the tuto).

Added boost::ublas::vector example to test_signalcast.

    * src/CMakeLists.txt, link to dl,
    * unitTesting/CMakeLists.txt.

Merge the florent branch.
Makes the test_depend.cpp test works.

Added unit test of the signal casting facility. Not exporting the SignalCastRegister class anymore (inlined in the .h).

- signals dependency testing
- factory testing (needs some SOT shared libraries to work though)

Renamed dynamic-graph-API.h to dynamic-graph-api.h in every header file.

The package name is now dynamic-graph (this still needs to be changed in the git repository). Updated source files to reflect that change. Clarified CMakeLists, explicited cpp source files for libraries.

Shell (ok)
Factory (currently needs sotGainAdaptive to compile, will change to another entity soon)
