Initial version of SHE Correlator

plus Config.xml.she based on old-style map and cal from dubna
Work on SheCorrelator
SheCorrelator beta version

* low energy cut for alphas
* human readable chains
* saturation handling
* front-back, dssd-si timing check
* dE condition on low energy (<15 MeV) events
* working correlator for dssd

* CALIBRATION IS NEEDED!
Pileups handling in Dssd4SHE

StripEvent added to keep information, the pileups are
now treated as any other events.

There is a question (problem?!) of calibrating the traces.
Also, there is no calibration for log range and the linear
range is not very well calibrated. At this point the "fission"
located in the code events make no sense
