  Modification to the re-usable Underworld SLE XML files:
    * Enforcing that each element must make a non-zero contribution
    to the K and g global matrices in the StokesFlow system.
    * Made it explicit that non-zero contributions from elements
    are OK for the compressibility matrix.
    * Not sure about the preconditioner in the Stokes SLE - so left
    open the possibility of all-zero assembly contributions.
