Minimal Surfaces

Another idea for MoI, by stressing nature again, could be based on 'minimal surfaces' as an optional style for the 'loft' tool.

Instead of choosing 'Normal', 'Loose' or 'Straight' a new 'Soap Bubble' function would calculate a surface in between
profile sections which would gain to be minimal in its surface area and therefore in its lowest 'energy level' as if it was a
soap bubble skin.

Maybe an accurate calculation of each of those surfaces would take an infinite time to be solved, yet there might be
simplifications possible to get a 'close to' but faster result.

The outcome of such a function, besides its inherent beauty, could be useful to those who seek for a good optimisation
of their models in terms of minimalism.
