Title: Camera lookAt

Ensure that the camera axes are orthonormal after calling `Camera.lookAt`.

@mramato This pull request and #223 should handle all of the culling issues in the viewerCamera branch. The culling plane computations depend on the axes being orthonormal and it was possible that they weren't if you use `Camera.lookAt`. The spindle controller expects the axes to be orthonormal and corrects them if they aren't which explains why rotating at all after loading IndiaCoverage.czml fixed the problem.
