/**
 * \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:
 *
 *     xxxx xxxx xxxx xxxx xxxx xxxx 
 *     |||| |||| |||| |||| |||| ||||_ 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)
 *     |||| ||||_____________________ 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)

229			* \brief Class to describe tracker LEVEL2 data.
230			*
231			* A tracker events is defined by some general variables, plus the collection of all the fitted tracks and all
232			* single clusters on X and Y views.
233			* Tracks and single clusters ("singlets") are described by the classes TrkTrack and TrkSinglet respectivelly.
234			*
235			* Each track may have an "image", due to the ambiguity on the Y view, which is stored also.
236			* Thus, the number of stored tracks ( ntrk() ) differs from the number of "physical" tracks ( GetNTracks() ).
237			* Proper methods allow to sort tracks and select the physical ones ( GetTracks() ).
238	pam-fi	1.28	*
239			* The event status indicates the processing status of data from each DSP, according to the following
240			* notation:
241			*
242			* xxxx xxxx xxxx xxxx xxxx xxxx
243			* \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\|_ 0 missing packet
244			* \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|__ 1 CRC error
245			* \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\| \|\|___ 2 on-line software alarm (latch-up, timeout ecc...)
246			* \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\| \|____ 3 jump in the trigger counter
247			* \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\|______ 4 decode error
248			* \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|_______ 5 n.clusters > maximum number (level1 processing)
249			* \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\| \|\|________ 6
250			* \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\| \|_________ 7
251			* \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\|___________ 8 n.clusters > maximum value (level2 processing)
252			* \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|____________ 9 n.couples per plane > maximum values (vector dimention)
253			* \|\|\|\| \|\|\|\| \|\|\|\| \|\|_____________ 10 n.doublets > maximum values
254			* \|\|\|\| \|\|\|\| \|\|\|\| \|______________ 11 n.triplets > maximum values
255			* \|\|\|\| \|\|\|\| \|\|\|\|________________ 12 n.yz-clouds > maximum values
256			* \|\|\|\| \|\|\|\| \|\|\|_________________ 13 n.xz-clouds > maximum values
257			* \|\|\|\| \|\|\|\| \|\|__________________ 14 n.candidate-tracks > maximum values
258			* \|\|\|\| \|\|\|\| \|___________________ 15 n.couples per plane > maximum values (for Hough transform)
259			* \|\|\|\| \|\|\|\|_____________________ 16
260			*
261			*
262			* For all data processed before June 2007 the event status was coded according to
263			* a different rule:
264			*
265			* Status of level1 processing
266			* 0 -- OK
267			* 1 -- missing packet
268			* 2 -- 1 CRC error
269			* 3 -- 2 on-line software alarm (latch-up flags asserted or n.transmitted-words = 0)
270			* 4 -- 3 jump in the trigger counter
271			* 10 -- 4 decode error
272			* 11 -- 5 n.clusters > maximum number (for level1 processing)
273			* Status of level2 processing
274			* 21 -- 0 n.clusters > maximum value (for level2 processing)
275			* 22 -- 1 n.couples per plane > maximum values (vector dimention)
276			* 23 -- 2 n.doublets > maximum values
277			* 24 -- 3 n.triplets > maximum values
278			* 25 -- 4 n.yz-clouds > maximum values
279			* 26 -- 5 n.xz-clouds > maximum values
280			* 27 -- 6 n.candidate-tracks > maximum values
