Fixing Landmarks
Image of things to try 
Description
At the end of each tiling or iteration, a form of find_nofit (T or P) is used to check for bad landmarks. A common find_nofit output will look soemthing like this:
The four main types of outputs are:
- ! - the landmark was deleted
- . - the landmark has overlaps
- (space) - the landmark has minor error (don't worry about it).
- * - the landmark has a major error and must be fixed.
