* Triangles to half-edges * Half-edges to triangles * Triangles to adjacent triangles * Points to half-edges * Half-edges to Voronoi cells
* Summary at end links to sample functions for {edge,triangle,point}
to {edge,triangle,point} functions.
* Some names were YFromX and some were XToY. Change them to YFromX.
* Change cellEdgeIds to edgesAroundPoint. It's not edgesFromPoint
because it doesn't actually take a point id; it takes an incoming
edge id so I wanted the name to be a little different to reflect
that.
* Major sections will be linkable (but the anchors aren't exposed anywhere) * Also fix typo in anchor "edges-to-edges" should have been "edge-to-edges"
* Previously pointsOfTriangle returned point x,y but it's more useful to return point ids so that it can be used for traversing the graph.
