Worked at updating the box tool to use the latest rectangle code that has two points and a direction, updated also the Lua code for it.
Pulled the constraints functionality code (circle fixed radius, line fixed length, rectangle fixed width and height), reviewed code and merged to devel repository code.
Fixed the extrude broken tool after merging. This functionality is ready for merge window.
Will continue with making a function that knows how to keep an edge to point constraint to have it for the merge window from Friday. Also will prepare the box tool code for merging.
