Public Member Functions
	TetgenMesh ()
	Empty constructor.

	TetgenMesh (const std::string &node_file_name, const std::string &element_file_name, const std::string &face_file_name, TimeStepper *time_stepper_pt=&Mesh::Default_TimeStepper, const bool &use_attributes=false)
	Constructor with the input files.

	TetgenMesh (tetgenio &tetgen_data, TimeStepper *time_stepper_pt=&Mesh::Default_TimeStepper, const bool &use_attributes=false)
	Constructor with tetgenio data structure.

	TetgenMesh (const std::string &node_file_name, const std::string &element_file_name, const std::string &face_file_name, const bool &split_corner_elements, TimeStepper *time_stepper_pt=&Mesh::Default_TimeStepper, const bool &use_attributes=false)
	Constructor with the input files. Setting the boolean flag to true splits "corner" elements, i.e. elements that that have at least three faces on a domain boundary. The relevant elements are split without introducing hanging nodes so the sons have a "worse" shape than their fathers. However, this step avoids otherwise-hard-to-diagnose problems in fluids problems where the application of boundary conditions at such "corner" elements can overconstrain the solution.
