History (interface to DB)

[bholt]

"Status" loses track of jobs after they finish. Need a way to query the database to find finished jobs.

• [x] Make it a Sequel::Model so we can query the dataset directly
• [ ] Helpers to find most recent jobs and show relevant fields to distinguish them.
• [x] Add link to output file and add helpers to read them

See Igor::results(): creates a Sequel::Model out of dataset, allow arbitrary filtering beforehand with block, and then user can interact with the Model at their leisure.

Punting on having "helpers" to show recent jobs--can't figure out a way to support it that doesn't limit functionality of resulting Model instance. Instead, just have user save a custom Model instance with correct filtering returned by results:

$recent = results{|t| t.order(:run_at).select(:scale, :nnode, :ppn, :max_teps).limit(5)}
