Geometry_Engine: Simplify volume into planar surface

It is quite usual to have multiple surfaces or a volume describing a certain geometry, which needs to then be simplified.
I often need to simplify this to grab one surface of interest. So I created a GH component to evaluate the area of the surfaces, find the largest ones (to avoid grabbing the smaller surfaces that build the volume), and evaluate and select the max Z component.
Do we think this would be useful as part of the BHoM?

Start by opening the attached Volume_to_Single_Surface.zip and reviewing the component's current behavior. Compare its largest-surface and maximum-Z selection approach with the BHoM_Engine geometry APIs, then establish the expected behavior and integration point before implementing anything. Done means the proposed volume-to-single-surface operation has an agreed scope and matching validation.
