Toward generic factory

Allows to typedef a factory for CreatorCallback with multiple input arguments.

The main change is that when typedef a new kind of factory the template parameter TypeInput must embed cv-qualifier, reference, pointer etc.

Update the SensorFactory to be a simple Factory typedef .
