proposed changes to configuration format

[K20shores]

Changes:

• version listed at top
• removed top level camp-data
• every reaction not involving aerosols has products and reactants keys. The type determines how they are used
• extraneous information not related to mechanisms can be added with two underscores __, like the absolute tolerance which is a solver parameter
• Species don't need to specify which phase they are in
• every reaction can now have an optional label called name
• Time units can no longer be specified
• now we have explicit arrays for species, reactions, phases, meaning we no longer need TYPE keys for anything except reaction types
• Removed Ternary Activation in favor of Troe; the only difference was the presence of M, which can be added
• Used full names for exp (exponential) and coeff (coefficient)
• Renamed Wennburg_NO_RO2 and Wennburg_Tunneling to Branched_NO_RO2 and Tunneling
• Removed the ability to split species, phases, reactions, across multiple files. Applications that use the format will have to configure that

@jcurtis2 @mwest1066, if you get a chance, I'd appreciate your feedback on these proposed changes.

And as an FYI, this repository will also publish a tool that parses these files and returns all of the data in arrays of structs for solvers to do what they will with

this looks great to me!
