Add binding for G4MultiSensitiveDetector

[bnara]

My model needed G4MultiSensitiveDetector. I based this off the existing binding for G4MultiFunctionalDetector.

Reading up on what this does now, I think this is for internal use only. When one passes multiple G4VSensitiveDetector to its G4VUserDetectorConstruction this will accommodate them automatically in a vector. Would you mind sharing how you intended to use it? And can you achieve a similar result by calling SetSensitiveDetector multiple times in a row with all G4VSensitiveDetectors you are planning to add to the logic volume?

Thanks for adding the iterator!

I am using G4MultiSensitiveDetector to effectively assign multiple instances of G4VSensitiveDetector to a single G4LogicalVolume.

I don't believe the same result can be achieved by calling SetSensitiveDetector multiple times:
G4LogicalVolume.cc#L478

Ahh I see, you are adding it manually to the G4LogicalVolume via its member function. While I think this method is the preferred way G4VUserDetectorConstruction.cc#L217 and would automatically put multiple G4VSensitiveDetector in a G4MultiSensitiveDetector, I still think binding G4MultiSensitiveDetector might be useful when one tries to manipulate it later. Thanks

Thanks! I didn't know about G4VUserDetectorConstruction::SetSensitiveDetector(). In my model, I create and initialize the sensitive detectors at a later stage following geometry construction, so I ended up directly using G4MultiSensitiveDetector.
