> Currently {{Range.subtractContained}} returns incorrect results if minuend
> range covers full ring and:
> * subtrahend range wraps around. For example, {{(50, 50] - (10, 100]}}
> returns {{\{(50,10], (100,50]\}}} instead of {{(100,10]}}
> * subtrahend range covers the full ring as well. For example {{(50, 50] - (0,
> 0]}} returns {{\{(0,50], (50,0]\}}} instead of {{\{\}}}
