// - BuildCrossSectionForMaterials method was revised in order to calculate the
// logarithmic values of the loaded data.
// It retrieves the data values from the G4EMLOW data files but, then, calculates the
// respective log values and loads them to seperate data structures.
// The EM data sets, initialized this way, contain both non-log and log values.
// These initialized data sets can enhance the computing performance of data interpolation
// operations
