Worked at fixing the Cut functionality, it started to cover well situations when it is invoked by a parametric modeling propagation. When Cut is applied on a scene it stores the objects affected by the operation and later if Cut is modified it is applied again on the objects stored. Objects added after the Cut or not affected when it was applied for the first time will not be affected later.
Implemented a first version of Delete. If a shape is selected and the Del key is pressed the shape is removed. Will finalize it tomorrow by implementing a modifier for it, task estimated to take 1-2 hours.
Will also work at improving the geometric solver and the magic point drawing.
