This brings puzzles up-to-date with upstream revision 2d333750272c3967cfd5cd3677572cddeaad5932, though certain changes made by me, including cursor-only Untangle and some compilation fixes remain. Upstream code has been moved to its separate subdirectory and future syncs can be done by simply copying over the new sources. Change-Id: Ia6506ca5f78c3627165ea6791d38db414ace0804

<h1><a name="C18"></a>Chapter 18: <a name="i0"></a>Untangle</h1>

You are given a number of points, some of which have lines drawn between them. You can move the points about arbitrarily; your aim is to position the points so that no line crosses another.
