// History:
// -----------
// 31 Jul 2001   MGP                 Created
//  9 Mar 2008   MGP                 Cleaned up unreadable code modified by former developer
//                                   (Further clean-up needed)
// 15 Jul 2009   N.A.Karakatsanis    New methods added for loading logarithmic data
//                                   to enhance computing performance of interpolation
