static final Comparator<LongInterval>	LENGTH_COMPARATOR	A comparator between intervals based on their length.
static final LongInterval	MINUS_INFINITY	A singleton located at −∞.
static final Comparator<LongInterval>	STARTS_AFTER	A comparator between intervals defined as follows: [a..b] is less than [a'..b'] iff the first interval starts after the second one, that is, iff a' < a.
