Detailed Description

A helper class for ca::tools::WindowFinder to handle a particular expression (dx vs. x0 etc.) and all related methods to work with it.

Note: DISTANCE (expression, axis) – dx or dy, signed distance between the extrapolated point and real MC-point PARAMETER (expression, axis) – x0 or y0, a parameter, vs. which the distance is studied
