     28// ===========
     29//
     30// Trains a random forest for disp estimation.
     31//
     32// The additional code below shows how the MagicCuts can be used in
     33// training and testing. There is also code which allows to change the
     34// slope of the input spectrum. If a min- or max-break energy is given
     35// the new slope is only applied in this region. Further possibilities
     36// for additional cuts are shown.
     37//
     38// SequencesOn:   Monte Carlo Sequences used for training
     39// SequencesOff:  Monte Carlo Sequences used for testing
     40//
     41// Use:
     42//  opt.AddPreCut    to use cut for test and training
     43//  opt.AddTestCut   to use cut for test only
     44//  opt.AddTrainCut  to use cut for train only
     45//  opt.AddPreTask   a task executed before filling the matrix/evaluating the RF
     46//  opt.AddPostTask  a task executed before training, after evaluating the RF
