Visualising Julia arrays

A convenience function, vtk_write_array, is provided to quickly save Julia arrays as image data:

p = rand(100, 100, 100)
vtk_write_array("filename", p, "Pressure")

This may be useful for visualising the data contained in a Julia array.

Writing multiple arrays

Multiple arrays can be given as a tuple. For instance,

vtk_write_array("filename", (u, v), ("u", "v"))

In that case, the arrays must have the same dimensions.
