Atgeirr Flø Rasmussen 2f14ed70c4 Modified compressible transport src term.
Using surface volume for injection rather than reservoir volume.
Chase change in class TransportModelCompressiblePolymer and
function computeInjectedProduced().

Also changed interface to computeInjectedProduced() to take state
rather than individual state variables.
