58//
59// Class Description:
60//
61// It is the unified energy loss process it calculates the continuous
62// energy loss for charged particles using a set of Energy Loss
63// models valid for different energy regions. There are a possibility
64// to create and access to dE/dx and range tables, or to calculate
65// that information on fly.
