+<h3>Testcase</h3>
+
+The testcase we will be solving is for a circular (in 2d) or spherical
+(in 3d) obstacle. Meshes for these geometries will be read in from
+files in the current directory and an object of type HyperBallBoundary
+will then be attached to the triangulation to allow mesh refinement
+that respects the continuous geometry behind the discrete initial
+mesh.
