Handle run properly !

[remyzorg]

To share signals between host and calls, it is possible to use an object interface for program descriptions too. It is then possible to provide an instanciation methode p#create to the user and an instanciation function p#create_run that take different arguments. I one case i takes only signal initial values and in the other case it takes signals structures.

Just beware that p#create_run must ignore animate

• Object interface for create and create_run :
• X Remove parameter to signal set method if the signal carries unit > not possible
• Handle Scheduling for run
