Is your feature request related to an enhancement? Please describe.

This is a single issue that lists a number of additional statistics of interest:

• [ ] OBB/AABB aspect ratio per surface/ per volume
• [ ] Ratio of OBB/AABB volume per surface/volume
• [ ] surface area to volume ratio per volume
• [ ] Ratio of volume to OBB/AABB volume per volume
• [ ] PDF of triangle area (whole model & per surface/per volume)
• [ ] ratio of area of smallest triangle/surface to model scale length (AABB volume?)

This will provide more insight into model features that might influence overall performance and robustness.

Describe the solution or outcome you'd like.

Each statistic can be added as people are available to do so.
