reads all the pictures in PICTLIST and landmarks in LMKLIST.TXT
Choice, solve for rotation rate (or not)
Keep iterating.
1st, asks for epoch. Give a UTC in the vicinity (Dec 2011).
Fixed W (rotation rate). At first, light curve data is better, so let others define it.
Follows those landmarks as the pictures rotation. Finds rotation and landmark position in body fixed frame.
(uses some algebra trick)
Converges in 2 iterations. Two possibilites (solve for Ra/Dec/Rate) (solve for Ra/Dec)
