Provides constrained triangulation of polygons. Ear cutting (or
ear clipping) applies constrained triangulation by successively 'cutting'
triangles from a polygon defined by path/s. Holes are supported by introducing
a bridge segment between polygon paths. This package wraps the 'header-only'
library 'earcut.hpp' < https://github.com/mapbox/earcut.hpp.git> which includes
a reference to the method used by Held, M. (2001)
