Just an example of how to use the FMM on a triangular mesh using EikMesh.
The following tasks are executed:
(1) load the planar straight-line graph from a file (the definition of the spatial domain)
(2) generate a mesh using EikMesh (if FMMTriangulationExamples#visualize is true this is displayed)
(3) define a target area (polygon)
(4) apply the FMM on a triangular mesh
