Corrected a few issues with the utilisation of the tracking within the nearWallFields function object. The tracking is now done over a displacement from the initial location, which prevents trying to track to a location outside the mesh when the patch face is warped and the centre lies outside the tracking decomposition. Also fixed the end criteria so that it does not suffer from round off error in the step fraction. The upshot of these changes is that the faces on which the near wall cells were not being set are now being set properly, and uninitialised data is no longer being written out.
