nonwrapping_range<T> and related templates represent mathematical intervals, and are different from C++ ranges. This causes confusion, especially when C++ ranges and the range templates are used together. As the first step to disentable this, introduce a new interval.hh header with the contents of the old range.hh header, renaming as follows: range_bound -> interval_bound nonwrapping_range -> nonwrapping_interval wrapping_range -> wrapping_interval Range -> Interval (concepts) The range alias, which previously aliased wrapping_range, did not get renamed - instead the interval alias now aliases nonwrapping_interval, which is the natural interval type. I plan to follow up making interval the template, and nonwrapping_interval the alias (or perhaps even remove it). To avoid churn, a new range.hh header is provided with the old names as aliases (range, nonwrapping_range, wrapping_range, range_bound, and Range) with the same meaning as their former selves. Tests: unit (dev)
