Changed buildEnv in conclusion

Now we return the filled conclusion base_env instead of self if
both paramaters are empty
I hope this makes sence
Fixed simulations so that they run

More debugging is needed for a smooth run
Cleanup cleanup, everybody everywhere
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

Changed the way uncertain quantities are added

I check to see if the other even has an uncertainty!
Simulations work correctly

There is now a key error, working on debuging that
Working on adding the Argument RHS

Fixed a bug with the engine, however now we are throwing a key error
All rules working

Horray!
