Genome::Process

`Genome::Process` serves as a holder of metadata related to commands that run workflows.  It is in some ways a stripped down `Genome::Model::Build`.  It will make possible `genome model build view` like views for things such as `Genome::VariantReporting` or the data importing commands.
Fair enough!

In the past I've been persuaded to go along with `updated_at` by the argument that it occasionally comes in handy and never have I wished an object didn't have it when it did.  But it's probably not necessary.
