This merge brings a new, more resilient and feature-complete
corner-point processing. In particular, the new code features
exact, in-plane vertex coordinates for face nodes that arise as a
result of fault processing and which are not located on pillars.
Secondly, the resulting grid's cells are ordered lexicographically
with the I index cycling the most rapidly, followed by J and
finally K.
Finally, this merge also brings automatic handling of left-handed
coordinate systems which, until now, have produced negative cell
volumes as a result of face vertices being ordered such that
interface normals point from cell 2 to cell 1 in this case.
Left-handed coordinate systems are recognised using a simplistic
triple-product characterisation akin to the implementation of
function "processGRDECL" of MRST.
This code is now an (almost) exact replica of revision 1001 of
https://public.ict.sintef.no/viewvc/openrs/trunk/dune-cornerpoint/grid/preprocess/
The merge also removes opm/core/grid/cpgpreprocess/readvector*, so
remove tests/test_readvector.cpp (and accompanying Make rule) to
maintain a buildable tree.
