Revamp processes

[stvdwtt]

Right now every simulation has 5+ input processes:

• Model parameters
• Numerical parameters
• A process for every variable/equation
• Software
• Computing environment

However, since both parameters processes reference the input file, if either differ between runs, neither can be shared. It would make sense to merge them.

Somewhat similarly, I think it makes sense to merge the eqn procs and the software proc. If someone changes the app in any way, I think it is fine to have a different process. This should be somewhat rare.

The revamped approach would have three processes:

• Parameters
• App
• Computing environment

Conceptually these are cleaner and lead to less Materials Commons clutter.
