edgeIndexToFaceLoop Method

Given an edgeIndex (index into data.pointIndex), return the range of the edgeIndices of the containing facet.

• If an edge with edgeIndex k is found in the facet with facetIndex f, then the returned range r satisfies r.low = this.facetIndex0(f) <= k < this.facetIndex1(f) = r.high and can be used to iterate the facet's face loop. See facetIndex0.
