+<p> IntervalMap is a compact map for small keys and values. It maps key
+intervals instead of single keys, and it will automatically coalesce adjacent
+intervals. When then map only contains a few intervals, they are stored in the
+map object itself to avoid allocations.</p>
+
+<p> The IntervalMap iterators are quite big, so they should not be passed around
+as STL iterators. The heavyweight iterators allow a smaller data structure.</p>
