new stuff working on bowl-slosh
forgot to add back in saveqc
removed debugging output
compute aux with less roundoff discrepancies
rearranged to set aux 2/3 before cycling
fixed print statement
move call to topo_update out of loop on grids in gfixup
need additional call to setaux on coarse grid from filval if aux_finalized<2.  Tested with moving topo and gives slightly better results
new setaux call in filval changes nosetest output in tests/dtopo1
debugged to account for moving topo
fixed bug in new indexing for negative numbers
commented out 2nd copy of aux arrays used for testing
merged Marsha's auxpar into topotools branch to test, after fixing conflicts in gfixup and filval where we both fixed the same bug.  The auxpar branch copies aux files rather than recomputing topo when possible.
one more conflict resolved
