-Medial Axis Projection Quadrangle meshing algorithm
-***************************************************
-
-Medial Axis Projection algorithm can be used for meshing faces with
-sinuous borders and a channel-like shape, for which it can be
-difficult to define 1D hypotheses such that to obtain a good shape of
-resulting quadrangles. The algorithm can be also applied to faces with ring
-topology, which can be viewed as a closed 'channel'. In the latter
-case radial discretization of a ring can be specified by
-using *Number of Layers* or *Distribution of Layers*
-hypothesis.

-
-The algorithm provides proper shape of quadrangles by constructing Medial
-Axis between sinuous borders of the face and using it to
-discretize the borders. (Shape of quadrangles can be not perfect at
-locations where opposite sides of a 'channel' are far from being parallel.)

-
-The Medial Axis is used in two ways:
-
-#. If there is a sub-mesh on a sinuous border, then the nodes of this border are mapped to the opposite border via the Medial Axis.
-#. If there are no sub-meshes on sinuous borders, then the part of the Medial Axis that can be mapped to both borders is discretized using a 1D hypothesis assigned to the face or its ancestor shapes, and the division points are mapped from the Medial Axis to both borders to find positions of nodes.
