Many undeclared duplicate reactions in chemkin file

[rwest]

After 2.5 hours, my methylformate job reported:

    The model core has 101 species and 4708 reactions
    The model edge has 11324 species and 17960 reactions

When I try to run it through chemkin it finds 1230 undeclared duplicates. The ones I've checked all seem to be in the reverse of the direction which they duplicate.

Interestingly there are only 210 chebyshev reactions (a small fraction of 4708), and these all printed as irreversible (with => arrows).

Most of these are fixed after all yesterday's work. Some still creep in, from depository reactions.

After several days work, and a reasonably large restructuring of the logic flow (thanks Josh!), I think this is now closed! I think the last nail in the coffin was 4fac866
