Function discriminant analysis (FDA).

This simple classifier fits any user-defined TFormula (via option configuration string) to the training data by requiring a formula response of 1 (0) to signal (background) events. The parameter fitting is done via the abstract class FitterBase, featuring Monte Carlo sampling, Genetic Algorithm, Simulated Annealing, MINUIT and combinations of these.
