Class Bits

java.lang.Object
com.complexible.common.primitives.Bits
public final class Bits extends Object
Utility class for manipulating bits. TODO Pavel: I think this can be optimized. There're two many method calls to set bits, etc. We aren't usually using arbitrary masks and can have specialized methods for specific masks.
