public class MinMaxAmplitudes
Min/Max Amplitudes.
Extracts N minimum and X maximum amplitudes from a sample as features. If incoming sample array's length is less than N + X, it is adjusted to be N + X long with the length/2 value repeated N + X - length times.

TODO: needs improvement to select different amplitudes as we don't want 20 the same maximums or minimus if others are avaible.
