RangeSet
Do simple set operations on Ruby Ranges and RangeSets
RangeSet objects act like Ranges except that they may have any number of gaps.
Limitations
This library is tested against integer ranges for my use case, but any Comparable type should work, possible with a little bit of effort.
I have not implemented more of the Range interface in RangeSet than I needed. If you need additional functionality, pull requests are welcome.
