Voxelisation in FreeCAD - Test 3 : 3 Voxel Modes

Current workflow for comment / suggestion: -

1. Select the shape object to 'voxelise', click Voxel button
2. Can select the shape of voxel, like (App::Link to) a Group w/ 4 Walls, Windows, Slab etc.
3. Has 3 modes :-

1. Center : If Center of (the BoundBox of) voxel is within the Input Shape, it is shown
2. Any Corner : If Any Corner of (the BoundBox of) voxel is within the Input Shape, it is shown
3. All Corners : Only if All Corners of (the BoundBox of) voxel are within the Input Shape, it is shown

Proof of concept for fun. Calculation particularly for 'All Corners' mode become slow. Hope someone like to develop something more advanced in C++ for much better performance like what in Blender Test Feature added in SketchArchWB.

Forgot to explain -

1. Under the hood, pressing the button creates 2 objects
2. First is a 'VoxelPart' object with a propertyLink to an 'Input Shape Object'
3. Second is an App::Link which produce the Array of Voxels
   1. The VoxelPart calculates the placement of every Voxels
   2. It creates a Box, or copy the shape of 'VoxelObj' (usecase: point to a object with Shape, or to a Link to a Group containing a numbers of objects)
   3. The 2nd Object App::Link actually create the array of Voxels according to VoxelPart calculation
