Test case for indirect containment is incorrect

The beam should be contained in the space, not aggregated.

Also, there should be two interpretations of 'indirect' containment.

1. Interpretation 1: PASS - a beam in a space: Beam <-- RelAgg --> ElementAssembly <-- RelContain --> Space
2. Interpretation 2: PASS (or FAIL?) - a beam in a building: Beam <-- RelContain --> Space <-- RelAgg --> Building
