Detailed Description

Implementation of cellLooper. This one recognizes splitHexes and tries to make a cut such that if the neighbour was split (in a previous iteration) this one also gets split in the same direction so that the result will be a mesh without splitHexes.

'splitHexes' are cells of which the 'featureEdges' (see cellFeatures class) form a hex. The remaining non-feature edges are assumed to result from splitting the neighbour and this class tries to start from one of these and cut through to an opposite edge.

The current set of cuts (vertIsCut, edgeIsCut, edgeWeight) are not being used by this implementation.

All non-splitHexes are done by the parent classes.
