27  * @brief TIM file reader - the stage information for a stochastic programming instance in SMPS format
28  * @author Stephen J. Maher
29  *
30  * This is a reader for the time file of a stochastic programming instance in SMPS format.
31  * The three files that must be read are:
32  * - .cor
33  * - .tim
34  * - .sto
35  *
36  * Alternatively, it is possible to create a .smps file with the relative path to the .cor, .tim and .sto files.
37  * A file reader is available for the .smps file.
38  *
39  * Details regarding the SMPS file format can be found at:
40  * Birge, J. R.; Dempster, M. A.; Gassmann, H. I.; Gunn, E.; King, A. J. & Wallace, S. W.
41  * A standard input format for multiperiod stochastic linear programs
