Start work on determining rotation using quaternions only
Rotation was previously approximated using axis/angle
This change starts down the path of using quaternions exclusively.
This change appears to give at least as good as answers as the axis/angle
model in basic cases (also only tested with 1 lighthouse), but it is
currently much slower and runs in unpredictable time.
