+# demo of createpts / poisson_disk module using various arguments

+# output01* is just the distribution of vertices without connectings as Delaunay triangles
+# output02* connect the vertices as a Delaunay triangulation
+# output03* is the same as output02 except the resoltion is reduced from 0.1 to 0.05
+# output04* variable resolution mesh with target edge length defined in user_resolution_1.mlgi
+# output05* variable resolution mesh with target edge length defined in user_resolution_2.mlgi

+Note that there is a memory error of some kind.
