12  * Revision 1.7 2007/07/12 19:30:14 fisyak
13  * Add includes for ROOT 5.16
14  *
15  * Revision 1.6 2007/01/25 22:33:11 balewski
16  * add:
17  * - better writeup
18  * - new simpler to use method calculating dca fo track to strip, it is just a wrapper, some approximations were used, may fail at the sector boundary
19  *
20  * Revision 1.5 2003/10/15 15:28:53 wzhang
21  * updated for the new StEEmcSmdGeom
22  *
23  * Revision 1.4 2003/04/04 15:35:47 wzhang
24  * added SMD constants
25  *
26  * Revision 1.3 2003/03/22 22:44:57 zolnie
27  * make it standalone library
28  *
29  * Revision 1.2 2003/03/06 18:54:20 zolnie
30  * improvements for track/tower matching
31  *
32  * Revision 1.1 2003/02/20 21:26:58 zolnie
33  * added simple geometry class
34  *
35  * Revision 1.1 2003/02/20 21:15:16 zolnie
