Refresh the filter panel when new sim with new ds selected.
Merge branch 'master' of https://github.com/SCI-Utah/cnome
Try to get the field values for the filter from the cache first, instead from a

Create a field copy for each newly created filter.
Update the chart view when a new simulation is selected.
Reset the filter values after changing simulation.
1. Save and restore filters for each vie - still has a bug: user is not
notified to save the workspace when a filter is removed.
2. Added simulations combo-box with a delete button. The combo is not
visible until it's style would be corrected.
Some small fixes.
Flow: dynamic loading commodity values based on current simulation
