serialize a model version number for the simulation

This is to tie the output from a simulation to the exact version of the code
that generated it. In the future, this will help us detect results that might have
been 'tainted' by a bug in the simulation. It will also help us manage
backwards compatability if we want to be able to take runs originally saved
for an old version of the sim and re-run them with newer logic
store a serialized form of each run in the database
persistence layer for simulation run outputs
save run output to the database each time
move runs view to sim app
move the template to the matching location
better pattern for run workflow
menu cleanup
