-- Running test case: Set.prototype.take
PASS: Set can take `key`.
PASS: Set no longer has `key`.
PASS: Set can NOT take `key`.
PASS: Set can NOT take `DNE`, as it does NOT exist.

-- Running test case: Set.prototype.intersects
PASS: an empty set should not intersect another empty set.
PASS: a non-empty set should not intersect an empty set.
PASS: a set should intersect another set with the same values.
PASS: a set should not intersect another set with different values.
PASS: a set should intersect another set with same and additional values.
PASS: a set should intersect another set with same and different values.

-- Running test case: Set.prototype.isSubsetOf
PASS: an empty set should be a subset of another empty set.
PASS: an empty set should be a subset of a non-empty set.
PASS: a set should be a subset of another set with the same values.
PASS: a set should not be a subset of another set with different values.
PASS: a set should be a subset of another set with same and additional values.
PASS: a set should not be a subset of another set with same and different values.

-- Running test case: Set.prototype.equals
PASS: an empty set should be equal to another empty set.
PASS: a set should be equal to another set with the same values.
PASS: a set should be equal to another set with the same values in a different order.
PASS: a set should not be a equal to another set with different values.
PASS: a set should not be equal to another set with same and different values.

-- Running test case: Set.prototype.difference
Given a Set with values [], and another Set with values []:
PASS: Set difference should be [].

Given a Set with values [1,2,3], and another Set with values []:
PASS: Set difference should be [1,2,3].

Given a Set with values [], and another Set with values [1,2,3]:
PASS: Set difference should be [].

Given a Set with values [1,2,3], and another Set with values [2,3,4]:
PASS: Set difference should be [1].


-- Running test case: Set.prototype.firstValue
PASS: Set with values [] should have firstValue equal to undefined.
PASS: Set with values [1,2,3] should have firstValue equal to 1.

-- Running test case: Set.prototype.lastValue
PASS: Set with values [] should have lastValue equal to undefined.
PASS: Set with values [1,2,3] should have lastValue equal to 3.
