* Main class of the dynamic beading strategies.
*
* The input polygon region is decomposed into trapezoids and represented as a half-edge data-structure.
*
* We determine which edges are 'central' accordinding to the transitioning_angle of the beading strategy,
* and determine the bead count for these central regions and apply them outward when generating toolpaths. [oversimplified]
*
* The method can be visually explained as generating the 3D union of cones surface on the outline polygons,
* and changing the heights along central regions of that surface so that they are flat.
* For more info, please consult the paper "A framework for adaptive width control of dense contour-parallel toolpaths in fused
deposition modeling" by Kuipers et al.
* This visual explanation aid explains the use of "upward", "lower" etc,
* i.e. the radial distance and/or the bead count are used as heights of this visualization, there is no coordinate called 'Z'.
*
* TODO: split this class into two:
* 1. Class for generating the decomposition and aux functions for performing updates
* 2. Class for editing the structure for our purposes.

/* When removing a vertex, we check the height of the triangle of the area
being removed from the original polygon by the simplification. However,
when consecutively removing multiple vertices the height of the previously
removed vertices w.r.t. the shortcut path changes.
In order to not recompute the new height value of previously removed
vertices we compute the height of a representative triangle, which covers
the same amount of area as the area being cut off. We use the Shoelace
formula to accumulate the area under the removed segments. This works by
computing the area in a 'fan' where each of the blades of the fan go from
the origin to one of the segments. While removing vertices the area in
this fan accumulates. By subtracting the area of the blade connected to
the short-cutting segment we obtain the total area of the cutoff region.
From this area we compute the height of the representative triangle using
the standard formula for a triangle area: A = .5*b*h
