Generic Instance Method

# isSuperset(of:)

Returns a Boolean value that indicates whether the set is a superset of the given sequence.

## Parameters

`possibleSubset`

A sequence of elements. `possibleSubset` must be finite.

## Return Value

`true` if the set is a superset of `possibleSubset`; otherwise, `false`.

## Discussion

Set A is a superset of another set B if every member of B is also a member of A.

### Comparing Sets
