Added a node for nitrogen atoms at the level L2: and assigned it
preliminarily the values of the Cs-HHHH group to prevent errors about
not finding a group value and as a starting point for future nitrogen
thermo groups.

Changed 1,3_Insertion_CO2 to only insert in a CH bond

Currently only have data for CH bonds, but the group definition
allowed for CC bond insertion as well. Without data for such
insertions, estimates were used from the CH reactions, which were
much faster than expected. Unless this reaction is found to be
possible, the group will be defined for CH bonds only.
Add new group definition for 1,3_Insertion_CO2 into C-O bond.

In the previous commit, @pierrerlb modified this family to prevent
CO2 inserting into a C-C bond, by making it only insert into C-H bonds.

At the 8th US National Combustion Meeting we learned that CO2 can
insert into a C-O bond: the reverse reaction, decomposition of 
dimethyl carbonate into methoxymethane and CO2, is described in [1] 10.1021/jp312643k

This commit creates some group definitions needed to allow this.

Added Dimethyl Carbonate reaction to Seed Mechanism
Corrected the Dimethyl Carbonate decomposition rate.

* The A factor was off by a factor of 10 (typo?).
* The Ea was in the wrong units (they reported Ea/R in Kelvin)
* The source was not specified.

NB > this rate is at 0.5 atm.
Replaced Dimethyl Carbonate rate with high pressure limit.

Took this from the supplementary material.
Corrected new 1,3_Isertion_CO2 group definitions.
Added rate rule for 1,3_Insertion_CO2 into a C-O bond in methoxymethane.

This comes from doi:10.1021/jp312643k
Details in the longDesc
Created a training entry for 1,3_Insertion_CO2 into methoxymethane.

This is defined in the direction that the original paper specified it.
The training program can find the reverse if it needs.

Rank unknown.
Valid Temperature range estimated.
