This is the first draft of the Support Eraser tool. The plugin creates a cube mesh which has the `anti_overhang_mesh` decorator causing it to block the creation of support material for overhangs within its volume. This distinction is necessary to avoid confusing this behavior from actually erasing a _portion_ of a support structure. Some (non-necessary) improvements could be made such as: - Better graphical style - Discussion of whether the cube should be able to pass through the build plate or not - Possible improvements to the tool's icon - Placing the cube at a cursor click location
