===State in MRML===

Currently, Slicer uses the concept of '''active''' datasets (the active volume, an active model, and active fiducial list, etc.) Application-wide, only a single datatype can be active at one time. This set of active datatypes is represented in the '''vtkMRMLSelectionNode'''.

The fiducials module also uses the concept of '''selected''' fiducials within any fiducial list. Many command line modules use only selected fiducials in their processing.

We propose to collapse these ("active" and "selected") into one state variable and move that concept consistently into the codebase, which includes the following work:

* defining '''Selected=0 or 1''' on a vtkMRMLTransformableNode.
* modifying the ''vtkMRMLSelectionNode'' to include multiple selected objects within any datatype
* extending the ''vtkSlicerNodeSelectorWidget'' to include checkbuttons rather than radiobuttons for nodes that can have multiple selections
* Changing the term '''active''' to '''selected''' in the codebase, (Fiducials module, ROI module, SlicesControlGUI, ViewControlGUI, ApplicationLogic and MRML XML parsing). MRML XML parsing should continue to support the "active" tag to remain backward compatible.
* Building the selection logic that appropriately marks objects as selected or deselected.
* Encourage developers to conform to this convention of setting and using the '''Pick''' mode for selection instead of overloading the '''Transform View''' mode with hot-keys (provide example of how to get and set the mouse mode, and how to use the selection logic.
