Detailed Description

A basic space point reco hit. Uses a TVector3 for initialization.

This class can be used to calculate the distance (residual) of a track to a point in space.

It is a very basic example of a RecoHit. VirtSpacePointRecoHit is initialized by an ordinary 3-vector and has unity error matrix. It is also a good example which can be used to develop more realistic RecoHits.

Initializing constructor.

With a RecoHitProducer that works on a TClonseArray containing TVector3 objects this constructor allows the automatic conversion from a cluster class (here the TVector3) to a RecoHit (the VirtSpacePointRecoHit).
