Test Runner Not Detecting Equal Lists on Interval<Time>

[cmoesel]

When running the test CqlIntervalOperatorsTest:Expand:ExpandPerHour, the test runner reports:

Test CqlIntervalOperatorsTest:Expand:ExpandPerHour status: fail expected: { Interval[@T10, @T10], Interval[@T11, @T11], Interval[@T12, @T12] } actual: [ [Object], [Object], [Object] ]

My engine is returning { Interval[@T10, @T10], Interval[@T11, @T11], Interval[@T12, @T12] } and translating it to a list of Tuples since the CQL IG FHIR type mapping doesn't have a specific mapping for Interval<Time> (and since Period represents start/end as dateTime values):

Given the current guidance on mapping, this is the best way to represent a list of Interval<Time>.
