Technique by APL for putting landmarks on the limb and keeping the limb points part of the densify process.

• 1) Get the list of limb points -- standard limber or limbers 1) Use them directly or bin them (remember to use West Longitude) 1) Create a maplet on the limb even if you don't have any images. 1) Improve the height of the maplet in LITHOS when running "find_height", option 2

awk script to rebin things
