Flagged out part of the code that didnt do what it was supposed to do
 It tried to find 2 adjacent radical sites and make a double bond between them
 However, there is no cycling over the different resonance isomers
 and nodes are not updated after they have been changed making the new graph identical to the first graph
 A working code doing the same has been written long before in the generateResonanceIsomersFromRadicalCenter() subroutine
 but was flagged out due to wrong thermo for birads and unwanted reactions
Skip checking for the stablest resonance isomer once thermo for initial graph
is obtained from a thermo library.
Bug-fix: resonance isomers always include the original molecule when they exist and only then
This made the new conjugated ring code to add various similar species, as in this case only the resonance isomer
was added to the resonance isomer vector.

This also relates to previous commit: when resonance isomers existed, it was checking all of them for lowest thermo
unrelated to the fact if the original thermo was obtained from a library.
New change that might speed up the code a little bit in cases a lot of non-resonating radicals are present.

Old code always added the radical to a new resonance vector, while now this is only done when a first resonance isomer is found.
This can help bypassing some checks if(resonanceIsomers = null) speeding up the code and requiring less mem.
