// $Id$
// Category: plane
//
// Class AliMpPlane
// ----------------
// Class represents the plane composed of 4 sector positions:
// 
//   I.  FS                             II. |  I.
//  II.  BS inverted in x             _____ | ____
// III.  FS inverted in x, y                |
//  IV.  BS inverted in y              III. |  IV.
//   
// FS - front sector
// BS - back sector
