Added more exception catch codes in interpreter. Should now link correctly with boost libraries. Small debug output changes.

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

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

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

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

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.

API to access framework functions without sotInterpreter.
Should ease the port to more complex interpreters without favoring
the internal interpreter. The latter one is here for backward
compatibility. It will be removed.

This version compile but might not work yet.
(not tested).

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

* New class SignalCaster
* Re-added the get, set and trace commands to signals

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

	* dynamic-graph-API.h -> dynamic-graph-api.h.

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.

Configured dynamicGraph package and cmake files. Last-minute adjustment to code for SOT separation (SOT Break)
