/* Function: fann_get_cascade_candidate_limit

   The candidate limit is a limit for how much the candidate neuron may be trained.
   The limit is a limit on the proportion between the MSE and candidate score.
   
   Set this to a lower value to avoid overfitting and to a higher if overfitting is
   not a problem.
   
   The default candidate limit is 1000.0

   in the activation function array and 3 steepnesses in the steepness array, then there will be 
   2x3=6 different candidates which will be trained. These 6 different candidates can be copied into
   several candidate groups, where the only difference between these groups is the initial weights.
   If the number of groups is set to 2, then the number of candidate neurons will be 2x3x2=12. The
