Added some specific convertion for vector, matrix and double signal, from C to Python (to avoid unnecessary convertion through strings.

       This function is equivalent to print() under python,
       is equivalent to str() in dg-python.

	  Executable dg-python emulates a minimal python interpreter.
	  The interpreter is able to
	    - execute single statements: (import, print,...),
	    - evaluate expressions.
	  Expressions and statements are separated by semi-colons. Several
	  statements and/or evaluations between two semi-colons yield an
	  undefined behavior.

    C++ entity might still be in use.
