* src/signal/signal-caster.cpp.

     * src/signal/signal-caster.cpp: when type is not registered.

   * include/dynamic-graph/signal-caster.h,
   * include/dynamic-graph/signal.t.cpp.

     * include/dynamic-graph/exception-abstract.h,

     * include/dynamic-graph/exception-signal.h,
     * include/dynamic-graph/exception-traces.h,
     * include/dynamic-graph/signal-caster.h: This enables uses to catch
       a broader class of exceptions with messages using what() method.

    * src/signal/signal-caster.cpp.

     * include/dynamic-graph/exception-abstract.h,
     * src/exception/exception-abstract.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.

tracer-real-time needs tracer.lib

The correct .so files for the plugins are now generated.

	  * include/dynamic-graph/signal-base.h,
	  * include/dynamic-graph/signal-ptr.h,
	  * include/dynamic-graph/signal-ptr.t.cpp,
	  * include/dynamic-graph/time-dependency.h,
	  * include/dynamic-graph/time-dependency.t.cpp,
	  * src/dgraph/entity.cpp, dependancy -> dependency,
	  * unitTesting/test_depend.cpp: makes the test_depend.cpp test works.

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

	    * signal-time-dependent.h: new.

	 * contiifstream.h: re-indent and remove trailing white spaces.

     * include/dynamic-graph/contiifstream.h,
     * src/debug/contiifstream.cpp.

     Otherwise, the package does not compile in debug mode.
