Changed mole fractions to increase amount of OH.

If we have more OH and less nonadiene, maybe stuff will 
react with OH rather than the larger radicals (which is 
causing strange species formation).
Results of a partial run with modified mole fractions.

Still making weird things, ended job early.
Removed some reaction families.

As per Fariba's suggestion, remove families making weird 
things so that we build a simpler model faster.
Result of run with removed reaction families.

Core: 27 species, 88 rxns
Edge: 6006 species, 58172 rxns

Ran for 7 hours. 

Some species still a bit weird looking, especially via 
disproportionation. Many with triple bonds.
