public final class BendableBigDecimalScore extends AbstractBendableScore<BendableBigDecimalScore> implements FeasibilityScore<BendableBigDecimalScore>
Score is based on n levels of BigDecimal constraints.
The number of levels is bendable at configuration time.
This class is immutable.
The getHardLevelsSize() and getSoftLevelsSize() must be the same as in the
BendableScoreDefinition used.

When rounding is needed, each rounding should be floored (as defined by Math.floor(double)).
The length of the returned array must be stable for a specific Score implementation.
For example: -0hard/-7soft returns new int{-0, -7}
The level numbers do not contain the Score.getInitScore().
For example: -3init/-0hard/-7soft also returns new int{-0, -7}

compareTo in interface Comparable<BendableBigDecimalScore>public String toShortString()
ScoreObject.toString(), but trims score levels which have a zero weight.
For example 0hard/-258soft returns -258soft.
Do not use this format to persist information as text, use Object.toString() instead,
so it can be parsed reliably.
