StringFieldEditor shows initial entry, but FieldSpinners do not. Still trying to figure out why. Added border panels around the Field and Data Panels. Field and Data panels not shown if not field or data parameters are requested.
DataComboBox has more consistent size now. Created DataFieldFunction to test function dialog window with both data and field arguments. appears to work
Field spinners behaving a bit better. Still working on initial value display
fixed FieldSpinners not showing initial value bug.
Removed remaining print statements used to debug
Added close button to DataTabs. Will look at why tab component slightly resizes when button icon changes.
Working on DataListPanel. It succesfully displays data from the core but need  to work on some sizing problems.
