Variables in components that don't exist

[orichters]

This definition of components of Emissions|{Level-1 Species} is a bit pointless given that Level-1 Species do not even have these subvariables.

I am not sure, but I think one needs to either add the components part only for {Level-2 Species}, or somehow in post-processing make sure that only variables that are defined in the template can be used in the components.

Thank you
