Determines whether this instance is non-empty subset of the specified
range. All values in this range must be within the other range.
Note: For practical reasons, this isn't conforming strictly to
the mathematical definition, where an empty set is considered to be
a subset of any set. However, two equal ranges will be considered
to be subsets of one another.
