Added in the scaffolds for several tables, including throughputs, throughput_metrics, commodities, units_of_measures, and measures_types, and raked those tables into the database.
Added in views for the measure_types table.
Added in views around the units_of_measures table.
Cleaned up the units_of_measures views and controllers, as well as overhauled the commodities views.
Added in the views for the throughput_metrics table.
Lots of work on the throughputs table and views here.  Added in the 'value' field into the throughputs table, generated a default view, and tied in processing units to a specific throughput.  Throughputs is still a work in progress, though, additional work is needed to polish it off.
Renamed a column in the throughputs table to allow for easier connections between the models.  Completed work on the controller for the throughputs table.
