Module rmap 

A collection that manages disjoint, inclusive ranges [start, end].

Design

• Ranges are stored in ascending order of their start points.
• Ranges are disjoint; there are no overlapping ranges.
• Adjacent ranges are merged (e.g., inserting 5 into [0,4] and then inserting 4 results in [0,5]).
• Each key in the BTreeMap represents the inclusive start of a range, and its corresponding value represents the inclusive end of that range.
