Implement Topological Operators for Time Types

[chaitan94]

• &&: Do the time values overlap (have points in common)? • @>: Does the first time value contain the second one? • <@: Is the first time value contained by the second one? • -|-: Is the first time value adjacent to the second one?

Invalid operations should throw accordingly
