`getFaceCenters()` is not dimensional

[guyer]

In the case of a dimensional mesh, getCellCenters() returns scaled values but getFaceCenters() does not:

>>> mesh = Grid1D(nx=3, dx=Variable("1. mum"))
>>> print mesh.getCellCenters()
[[ 0.5  1.5  2.5]] mum
>>> print mesh.getFaceCenters()
[[ 0.  1.  2.  3.]]
