ReferenceFinder 4.0.1

ReferenceFinder is a great tool that will help you because often in more complex origami models, one is faced with the difficulty of laying down creases that are in proportion with a central point or line, but which in turn might be somewhere in the middle of the paper.
Given coordinates, ReferenceFinder will outline, step-by-step, the folding sequence to reproduce that reference point with as much mathematical accuracy as possible.
ReferenceFinder immediately returns the 5 "best" short folding sequences that approximates that point or line.
The approximations are very good, often better than 1 part in 1000, which, in my experience, is about the limit of human folding precision. ReferenceFinder can parse simple algebraic expressions (thanks to a contribution from Carlos Furuti).
The default paper shape is a unit square, but you can change the dimensions for any rectangle (e.g., a silver rectangle or currency).
For each solution, ReferenceFinder reports the absolute error in distance, the rank (the number of folds needed), and the sequence of actions needed to construct the desired reference mark.
For more details, read the README.txt file that accompanies each of the download packages.
Enhancements:
- [RJL, all] Modified RefLine::DistanceTo() to properly handle the case where a line barely crosses the corner of the square; prior implementation gave incorrectly small results. Also updated the Help docs to reflect Justins discovery of the 7 Huzita axioms.
