SwiftRanges provides some kinds of range that are not implemented in Swift Standard Library.
It was originally written as a part of SwiftCGIResponder.

AnyRange: A type-erased range. (Deprecated)RangeDictionary: A collection likeDictionarywhose key is a range.GeneralizedRangeSet: A set that can contain multiple types of ranges. (Renamed fromMultipleRanges)
