std::list< TPCVoxel > marlintpc::HitDistributor::distributeHit	(	SimTrackerHit *	hit,
		double	sigmaTrans,
		double	sigmaLong = `0`
	)

Only function accessible from the outside.

Takes a hit and the diffusion parameters for input. Calls all the over function necessary, depending on the type of the pad layout.
