Cage Blender's monkey head

Start with: Blender's built-in test mesh: Add › Mesh › Monkey (named Suzanne) in a new General file. No file to download.

1. Install YmirCage as above, start a new General file, delete the default cube and add Add › Mesh › Monkey.
2. With Suzanne selected in Object Mode, open the YmirCage tab and keep the defaults (World, Padding 0, Resolution 2 × 2 × 2).
3. Click Fit Cage.
4. Select YmirCage_Suzanne, press Tab and move one corner point; then return to Object Mode and click Remove Cage.

Expected result: Fit Cage reports “created 'YmirCage_Suzanne' for 1 object(s)”. A 2 × 2 × 2 lattice exactly the size of Suzanne's bounding box (2.734 × 1.703 × 1.969 m) appears, and Suzanne's modifier list shows one Lattice modifier using YmirCage_Suzanne. Moving a corner point bends the head. Remove Cage reports that it removed 1 cage and 1 modifier; Suzanne is left with no modifier and its mesh was never applied or edited.
