A concrete implementation of TrackingRegion. Apart of vertex constraint from TrackingRegion in this implementation the region of interest is further constrainted in phi and eta around the direction of the region

constructor (symmetric eta and phi margins).
dir - the direction around which region is constructed
the initial direction of the momentum of the particle should be in the range
phi of dir +- deltaPhi
eta of dir +- deltaEta

vertexPos - the position of the vertex (origin) of the of the region.
It is a centre of cylinder constraind with rVertex, zVertex. The track of the particle should cross the cylinder
WARNING: in the current implementaion the vertexPos is supposed to be placed on the beam line, i.e. to be of the form (0,0,float)

ptMin - minimal pt of interest
rVertex - radius of the cylinder around beam line where the tracks of interest should point to.
zVertex - half height of the cylinder around the beam line where the tracks of interest should point to.
deltaEta - allowed deviation of the initial direction of particle in eta in respect to direction of the region
deltaPhi - allowed deviation of the initial direction of particle in phi in respect to direction of the region whereToUseMeasurementTracker: 1=everywhere, 0=outside pixles, -1=nowhere
