/**
 * \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)

253	* \brief Class to describe tracker LEVEL2 data.
254	*
255	* A tracker events is defined by some general variables, plus the collection of all the fitted tracks and all
256	* single clusters on X and Y views.
257	* Tracks and single clusters ("singlets") are described by the classes TrkTrack and TrkSinglet respectivelly.
258	*
259	* Each track may have an "image", due to the ambiguity on the Y view, which is stored also.
260	* Thus, the number of stored tracks ( ntrk() ) differs from the number of "physical" tracks ( GetNTracks() ).
261	* Proper methods allow to sort tracks and select the physical ones ( GetTracks() ).
262	*
263	* The event status indicates the processing status of data from each DSP, according to the following
264	* notation:
265	*
266	* xxxx xxxx xxxx xxxx xxxx xxxx
267	* \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\|_ 0 missing packet
268	* \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|__ 1 CRC error
269	* \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\| \|\|___ 2 on-line software alarm (latch-up, timeout ecc...)
270	* \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\| \|____ 3 jump in the trigger counter
271	* \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\|______ 4 decode error
272	* \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|_______ 5 n.clusters > maximum number (level1 processing)
273	* \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\| \|\|________ 6
274	* \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\| \|_________ 7
275	* \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|\|___________ 8 n.clusters > maximum value (level2 processing)
276	* \|\|\|\| \|\|\|\| \|\|\|\| \|\|\|____________ 9 n.couples per plane > maximum values (vector dimention)
277	* \|\|\|\| \|\|\|\| \|\|\|\| \|\|_____________ 10 n.doublets > maximum values
278	* \|\|\|\| \|\|\|\| \|\|\|\| \|______________ 11 n.triplets > maximum values
279	* \|\|\|\| \|\|\|\| \|\|\|\|________________ 12 n.yz-clouds > maximum values
280	* \|\|\|\| \|\|\|\| \|\|\|_________________ 13 n.xz-clouds > maximum values
281	* \|\|\|\| \|\|\|\| \|\|__________________ 14 n.candidate-tracks > maximum values
282	* \|\|\|\| \|\|\|\| \|___________________ 15 n.couples per plane > maximum values (for Hough transform)
283	* \|\|\|\| \|\|\|\|_____________________ 16
284	*
285	*
286	* For all data processed before June 2007 the event status was coded according to
287	* a different rule:
288	*
289	* Status of level1 processing
290	* 0 -- OK
291	* 1 -- missing packet
292	* 2 -- 1 CRC error
293	* 3 -- 2 on-line software alarm (latch-up flags asserted or n.transmitted-words = 0)
294	* 4 -- 3 jump in the trigger counter
295	* 10 -- 4 decode error
296	* 11 -- 5 n.clusters > maximum number (for level1 processing)
297	* Status of level2 processing
298	* 21 -- 0 n.clusters > maximum value (for level2 processing)
299	* 22 -- 1 n.couples per plane > maximum values (vector dimention)
300	* 23 -- 2 n.doublets > maximum values
301	* 24 -- 3 n.triplets > maximum values
302	* 25 -- 4 n.yz-clouds > maximum values
303	* 26 -- 5 n.xz-clouds > maximum values
304	* 27 -- 6 n.candidate-tracks > maximum values
305	* 28 -- 7 n.couples per plane > maximum values (for Hough transform)
