		const int	idx,
		const int	nsd,
		mshType &	mesh
	)

Read fiber direction data from a VTK VTU file and copy it into a mesh..

Data is stored in the mesh for all fiber direction files.

Mesh variables set mesh.fN - Fiber orientations stored at the element level.
mesh.fN shape is Array<double>(num_fiber_files*nsd, num_elems)

Arguments: file_name - The name of the VTK VTU file storing fiber direction data data_name - The name of the VTK Cell Data Array storing fiber direction data idx - The id used to identify a fiber file (0, 1, ..., number of fiber files - 1) mesh - The mesh to store the data into.
