	IDepoDriftCompare (double drift_speed=1.6 *units::mm/units::microsecond)
bool	operator() (const IDepo::pointer &lhs, const IDepo::pointer &rhs) const

Public Attributes
double	drift_speed

Detailed Description

Compare how "far" two depositions are from the origin along the drift-line (metric: dT + dX/V_drift) given a drift velocity. Note: if drifting is toward a "back" face of an anode then the drift speed should be negative in order to indicate drift is in the postitive X direction..
