index (or input) i that fulfills TARGET[i] >= VALUE, where '>=' is the
complement of ORDER. In other words, this function returns the leftmost index at
which VALUE can be inserted with keeping the order. Therefore, TARGET must be
monotonically non-decreasing with respect to ORDER.

This function returns END if VALUE exceeds TARGET[END-1]. Note that the range
[START, END) is half-open. END must be explicitly specified if TARGET is
function. KEY is applied to each element of TARGET before comparison."
