Merge branch 'develop' into resolution_base_on_target
* base the resolution for the LSQ6, LSQ12 and NLIN stages on the target input files (either the initial model, or the target file). Currently this is how the pipeline behaves in practice, and it's a lot easier to set it up this way, because the resolution can be determined on files that exist at graph creation time. There won't be any discrepency between that graph and the runtime stages.
