ear_gc

<p>A 'sfc_GEOMETRYCOLLECTION' of four-cornered triangles ('POLYGON')
created by ear cutting the North Carolina polygon from sf.</p>

Generate common data forms for complex data suitable for conversions and
transmission by decomposition as paths or primitives. Paths are sequentially-linked records,
primitives are basic atomic elements and both can model many forms and be grouped into hierarchical
structures.  The universal models 'SC0' (structural) and 'SC' (labelled, relational) are composed of
edges and can represent any hierarchical form. Specialist models 'PATH', 'ARC' and 'TRI' provide the
most common intermediate forms used for converting from one form to another. The methods are
inspired by the simplicial complex <https://en.wikipedia.org/wiki/Simplicial_complex> and
provide intermediate forms that relate spatial data structures to this mathematical construct.
