add information to VPTrackMonitor to study residuals
- replace
getResidual
function bynode.residual()
- add additional track information to node and track tuples
- add flag if residual is x- or y-residual
- add flag if track is only hitting left or right VELO half or if it is overlap track (based on code copied from @anbeck )
- add histograms of mean residuals as function of track slope
