Make computation running nicer
- make sure samples being run through components actually have filled in the values they say are required
- add waiting cursor & finish notifications on computation plan running
View selection/filtering improvements
- Make creating filters & views actually work from the GUI, at least in the simple case
- When a computation plan is created, create a filter and view devoted to looking at the data from that plan sanely
  - should maybe make the view workflow-based instead of comp plan based?
- auto-select appropriate view & filter after running a computation plan
