Concept definition

template<typename Shape>
concept geom::BoundaryMeasurableObject =  DimensionalObject<Shape> and
    requires (const Shape& s)
{
    { s.measure_boundary() } -> std::convertible_to<typename Shape::elem_t>;
}

Detailed Description

A shape which can measure its boundary.

For a 2D shape, this is its perimeter; for a 3D shape, this is its surface area; higher-dimensional shapes measure their (N-1)-hypervolumes.
