Detailed Description

Describes a simulated track segment in a z-plane modeling an ME0 chamber. It is modeled after CSCSegment, so it is a 4-dimensional object ( origin (x,y) , direction (x,y) ) Formally it must be defined as a LocalPoint and LocalError but we actually use the global coordinate system.
