Meshing Parameters
-------------------
maxh: float = 1e10
Global upper bound for mesh size.
grading: float = 0.3

and along edges. File must have the format:
nr_points
x1, y1, z1, meshsize
x2, y2, z2, meshsize
...
xn, yn, zn, meshsize
nr_edges
x11, y11, z11, x12, y12, z12, meshsize
...
xn1, yn1, zn1, xn2, yn2, zn2, meshsize
segmentsperedge: float = 1.
Minimal number of segments per edge.
quad_dominated: bool = False
Quad-dominated surface meshing.
blockfill: bool = True
Do fast blockfilling.
filldist: float = 0.1
Block fill up to distance
delaunay: bool = True
Use delaunay meshing.
delaunay2d : bool = True
Use delaunay meshing for 2d geometries.
Optimization Parameters
-----------------------

m .. move nodes
M .. move nodes, cheap functional
s .. swap faces
c .. combine elements
d .. divide elements
p .. plot, no pause
P .. plot, Pause
h .. Histogramm, no pause
H .. Histogramm, pause
optsteps3d: int = 3

optimize2d: str = "smcmSmcmSmcm"
2d optimization strategy:
s .. swap, opt 6 lines/node
S .. swap, optimal elements
m .. move nodes
p .. plot, no pause
P .. plot, pause
c .. combine
optsteps2d: int = 3
Number of 2d optimization steps.
elsizeweight: float = 0.2
Weight of element size w.r.t. element shape in optimization.
