Additional hard coded constrains for Intra_Diels_alder2
Before reacting the code will see how many bicyclic nodes are made in the reactants and forbid the reaction if this value is larger than 2.
Added a new resonance function that should avoid dubble counting of aromatics (e.g. napthalene) and other rings that are characterized by the
following bond structure single-double-single-double... with number of single bonds = number of double bonds
Few modifications:
1. Instead of printing rates for forbidden reactions, just omit the reaction
2. Hard coded double counting of some intra H abstractions
