/**
 * \brief Class to describe tracker LEVEL2 data.
 *
 * A tracker events is defined by some general variables, plus the collection of all the fitted tracks and all 
 * single clusters on X and Y views. 
 * Tracks and single clusters ("singlets") are described by the classes TrkTrack and TrkSinglet respectivelly.
 * 
 * Each track may have an "image", due to the ambiguity on the Y view, which is stored also. 
 * Thus, the number of stored tracks ( ntrk() ) differs from the number of "physical" tracks ( GetNTracks() ). 
 * Proper methods allow to sort tracks and select the physical ones ( GetTracks() ).
 *
 * The event status indicates the processing status of data from each DSP, according to the following
 * notation:
 *
 * LSB --> 0 missing packet
 *         1 CRC error
 *         2 on-line software alarm (latch-up, timeout ecc...)
 *         3 jump in the trigger counter
 *         4 decode error
 *         5 n.clusters > maximum number (level1 processing)
 *         6 
 *         7 
 *         8 n.clusters > maximum value (level2 processing)
 *         9 n.couples per plane > maximum values (vector dimention)
 *         10 n.doublets > maximum values
 *         11 n.triplets > maximum values
 *         12 n.yz-clouds > maximum values
 *         13 n.xz-clouds > maximum values 
 *         14 n.candidate-tracks > maximum values
 *         15 n.couples per plane > maximum values (for Hough transform)
 * MSB --> 16 
 *         
 *
 * For all data processed before June 2007 the event status was coded according to
 * a different rule:
 *
 * Status of level1 processing
 *  0 -- OK  
 *  1 -- missing packet
 *  2 -- 1  CRC error
 *  3 -- 2 on-line software alarm (latch-up flags asserted or n.transmitted-words = 0)
 *  4 -- 3 jump in the trigger counter
 * 10 -- 4 decode error
 * 11 -- 5  n.clusters > maximum number (for level1 processing)
 * Status of level2 processing
 * 21 -- 0 n.clusters > maximum value (for level2 processing)
 * 22 -- 1 n.couples per plane > maximum values (vector dimention)
 * 23 -- 2 n.doublets > maximum values 
 * 24 -- 3 n.triplets > maximum values 
 * 25 -- 4 n.yz-clouds > maximum values 
 * 26 -- 5 n.xz-clouds > maximum values 
 * 27 -- 6 n.candidate-tracks > maximum values 
 * 28 -- 7 n.couples per plane > maximum values (for Hough transform)

328			* A tracker events is defined by some general variables, plus the collection of all the fitted tracks and all
329			* single clusters on X and Y views.
330			* Tracks and single clusters ("singlets") are described by the classes TrkTrack and TrkSinglet respectivelly.
331			*
332			* Each track may have an "image", due to the ambiguity on the Y view, which is stored also.
333			* Thus, the number of stored tracks ( ntrk() ) differs from the number of "physical" tracks ( GetNTracks() ).
334			* Proper methods allow to sort tracks and select the physical ones ( GetTracks() ).
335	pam-fi	1.28	*
336			* The event status indicates the processing status of data from each DSP, according to the following
337			* notation:
338			*
339	pam-fi	1.35	* LSB --> 0 missing packet
340			* 1 CRC error
341			* 2 on-line software alarm (latch-up, timeout ecc...)
342			* 3 jump in the trigger counter
343			* 4 decode error
344			* 5 n.clusters > maximum number (level1 processing)
345			* 6
346			* 7
347			* 8 n.clusters > maximum value (level2 processing)
348			* 9 n.couples per plane > maximum values (vector dimention)
349			* 10 n.doublets > maximum values
350			* 11 n.triplets > maximum values
351			* 12 n.yz-clouds > maximum values
352			* 13 n.xz-clouds > maximum values
353			* 14 n.candidate-tracks > maximum values
354			* 15 n.couples per plane > maximum values (for Hough transform)
355			* MSB --> 16
356	pam-fi	1.28	*
357			*
358	pam-fi	1.39	* For all data processed before June 2007 the event status was coded according to

360			*
361			* Status of level1 processing
362			* 0 -- OK
363			* 1 -- missing packet
364			* 2 -- 1 CRC error
365			* 3 -- 2 on-line software alarm (latch-up flags asserted or n.transmitted-words = 0)
366			* 4 -- 3 jump in the trigger counter
367			* 10 -- 4 decode error
368			* 11 -- 5 n.clusters > maximum number (for level1 processing)
369			* Status of level2 processing
370			* 21 -- 0 n.clusters > maximum value (for level2 processing)
