Don't know what I did wrong, but I had to fix the same 'marker_ecf' undefined bug from:
1134684e0594d09b55adbfb7eb28260e0dcc210f
Added a basic ground view, locked at origin. Also updated the time control buttons a bit.
Added a way to set the user's current location. Ground Camera looks up through this location.
Merge branch 'MultiCamera'
