32// History:
33// -----------
34// 1 Aug 2001 MGP Created
35//
36// 09.10.01 V.Ivanchenko Add case z=0
37//
38// 9 Mar 2008 MGP Cleaned up unreadable code modified by former developer
39// (Further clean-up needed)
40//
41// 15 Jul 2009 Nicolas A. Karakatsanis
42//
43// - LoadNonLogData method was created to load only the non-logarithmic data from G4EMLOW
44// dataset. It is essentially performing the data loading operations as in the past.
45//
46// - LoadData method was revised in order to calculate the logarithmic values of the data
47// It retrieves the data values from the G4EMLOW data files but, then, calculates the
48// respective log values and loads them to seperate data structures.
49//
50// - SetLogEnergiesData method was cretaed to set logarithmic values to G4 data vectors.
51// The EM data sets, initialized this way, contain both non-log and log values.
52// These initialized data sets can enhance the computing performance of data interpolation
53// operations
