Detailed Description

STL generic algorithm function object. Used to select IKinematic objects below a threshold delta R. Specialised (7/7/2006 SD) to allow different dR limits in barrel and forward regions, without changing previous behaviour. If only 'barreldRLimit' is supplied in constructor, this is used as the overall dR limit
