// Enum AliMUONGeometryDirection
// -----------------------------
// Enumeration for the directions in a plane.
-// This method gives the direction where the pad size of the chamber is constant.
-// In other words this corresponds with the coordinate where the spatial resolution is the best.
-// Normally kDirY will correspond with cathode segmentation for the bending plane and
-// kDirX with cathode segmentation for the non bending plane
