41 //
42 // It is the unified energy loss process it calculates the continuous
43 // energy loss for charged particles using a set of Energy Loss
44 // models valid for different energy regions. There are a possibility
45 // to create and access to dE/dx and range tables, or to calculate
46 // that information on fly.
