// Class Description:
|
|
//
|
|
// A utility static class, responsable for the energy loss tables
|
|
// for each particle
|
|
//
|
|
// Energy loss processes have to register their tables with this
|
|
// class. The responsibility of creating and deleting the tables
|
|
// remains with the energy loss classes.
