Detailed Description

Gear geometry class - holds all geometry information about silicon strip sensors.

The data are taken directly from Gear xml file and values are saved in the system of units defined in PhysicalConstants.h. The local reference system is defined as follows: X-axis is perpendicular to the beam axis and to the ladder (sensor) plane; Y-axis lies in a ladder (sensor) plane and is also perpendicular to the beam axis; Z-axis is parallel to the beam axis(for zero theta); (0,0,0) point is positioned such as X, Y, Z coordinates are always positive. Strips are considered to be either perpendicular to the beam axis or parallel with the beam axis (SSDs) or both (DSSDs).
