rangeary 0.3.0

Rangeary is a sub-class of Array and represents any 1-dimensional multiple-range. For example, (x<4 and 7<x<=9). All the standard logical operations, such as negation and conjunction, are supported and can be used with conventional Ruby-style operators. Each range is represented as RangeExtd class (Extended Range), which is a sub-class of Range and supports exclude-begin and open-ended (to Infinity) ranges, and is downloadable from https://rubygems.org/gems/range_extd
