A rewritten Summary.cpp with some minor header modifications. Synposis of the new implementation: * Uses unordered_map< string, std::function > for dispatch, instead of multiple functions and a switch * Some poor man's function composition support has been added (privately) to avoid a lot of reptition in the post processing. * Functions assume they work over lists of wells instead of single wells being special cased - this means groups of well etc. can share implementation with single wells and field keywords. * Unsupported keywords are not written in the Summary file. Furthermore, some comments on special cases and overall approach and a generally more declarative implementation. This change is invisible to downstream developers. Users will obviously see no more garbage keywords.
