[C++] Short IntervalMap data structure implementation
/*
* NOTE 1: This works on VC++ but might need a little extra syntax to work on GCC.
* NOTE 2: It breaks when calling set_interval on the minimum key (std::numeric_limits<K>::lowest()) and maybe on the maximum key too.
*
* OPERATIONS:
*
* N = number of unique intervals. (Neighboring intervals with the same value are joined.)
* Iterators run in key-sorted order. (Or reverse, if you like - they're bidirectional.)
*
* get_min(): O(1)
