// Author........: Aleksander 豩rn

// Description...: Loads a set of (target, output) pairs, as
//                 output from a ROSETTA calibration curve with
//                 a single object per group.
//
//                 A third number per line may also be supplied, which
//                 indicates a sorting key the pairs are to be sorted
//                 by. The sorting key is typically an object index.
//                 This helps one to "auto-align" the pairs from
//                 different classifiers.
//
//                 Sorting can be turned off by the sort flag, even
//                 if sorting keys are present.
//
//                 The pairs are read as (output, target) if the
//                 swap flag is set.
