* Adding README.md file for GithHub page

* The code compile and run but still need confirmation that it work as
* expected
* Modification does not affect the usual single differential way of
* working

* double deletion of histogramms by Root and the cause a seg fault when
* leaving cint

 - in rare case wrong time was assigned to the wrong energy for Silicon
* Cosmetic change un TMust2Physics for better code readbility
