Changes in trigger:

Changes in trigger:
- Add initialization of Apt histograms in AliMUONTriggerLut (otherwise they
are "null" when created via AliMUONTriggerIO, eventhough they are not used
anymore)
- Modify the Compare function in AliMUONTriggerLut in oder to properly loop
over the TH3 bins
- Change destinations of GLOBAl and REGIONAL trigger configuration CDB files
in the AliMUONTriggerSubprocessor (the old destinations were not used, anyway,
when the calibration data was initialized) to the same locations were
identical objects are written by AliMUONCDB; remove old destinations in the
CDB (?)
- Add a new ROOT file for the trigger Look-Up-Table with all-pt and low-pt
cuts (the old one contains low-pt and high-pt cuts) to be used when the CDB
entry is created by hand using AliMUONCDB
- Update READMEtrigger with an explanation of the two LUT ROOT files
