Detailed Description
template<typename T, class Compare = std::less<T>>
class theplu::yat::utility::Segment< T, Compare >
a class for a Segment or Interval
A Segment is defined by its begin and end. The end is not included in the Segment, i.e., you could write the Segment as [begin, end). Type T must be comparable, optionally with a comparator Compare, which should implement Strict Weak Ordering..

This function takes two Segment and compare them with comparator Compare. If all elements in lhs is less than all elements in rhs, true is returned. In other words, false is returned if rhs.begin() is less than lhs.end().
The exception is if both lhs and rhs are empty Segment (i.e. begin equals end) and their begins and ends are equal, in which case false is returned. This exception implies that compare(x,x) always returns false.

- Returns:
- -1 if compare(lhs, rhs) is
true, +1 if compare(rhs, lhs) is true, and 0 otherwise

- Returns:
- -1 if element is less than all elements in segment, 0 if element overlaps with segment, and 1 otherwise.

template<typename T , class Compare >
- Returns:
- intersection of a and b. If a and b do not overlap an empty Section is returned (begin==end), but the exact value of begin is undefined.
