Quick Evaluate
==============
The Quick Evaluate page can be accessed as another tab alongside 'Console' and 'Recipes'. It can be used to evaluate expressions referring to values in the workspace.

Expressions can be added to the evaluation table by selecting one in the 'Available Expressions'. The expressions can be modified once inside of the evaluation table in order to add in an index or map key, such as would be required for expressions containing in [] (vector requiring integer index) or [''] (map requiring string key).

As the flowchart runs, the expressions will be continuously evaluated and refreshed to reflect their changing values.

Users can right click and select "Show Node in Quick Evaluate" to quickly filter the expressions in Quick Evaluate.

Click the Pose under the "Evaluated Value". There is no pose in the "Evaluated Result" because the index of occurrence is empty. The software does not know which pose to return.

If the target object is the tee on the top left, its index is 0. Enter 0 in the bracket of the occurrence under the "Expression" section.
