Value Range
Scala provided range structures (Range and NumericRange) are implemented more as collections and this class is designed to close this void focusing on generic range operations
Range is defined with the following defs:
startend,- and
ordering, which mks the above meaningful
Range has a notion that an element can be within the range, i.e. between start and end, or outside
Note. Range is implicitly converted to a let function, returning true if an element is within Range and false otherwise
