- create a new MeshTopologySelector base class. The existing GroupTopologySelector class now inherits from it, as does a new BoundarySelector class
- likewise, create a new MeshTopologySelectionMehchanic base class and have (existing) PolygonSelectionMechanic and (new) BoundarySelectionMechanic inherit from it
- the new Boundary classes use FMeshBoundary loops to define selectable loops rather than FGroupTopology
HoleFillTool:
- change to using BoundarySelectionMechanic instead of GroupTopologySelector
Misc:
- allow FMeshBoundaryLoops to fail untangling a loop with bowties but still continue processing other loops

ToolsFramework:
add UInteractiveCommand and UInteractiveCommandArguments types, base classes for 'interactive commands' which are intended to be used for atomic actions, ie stateless, no user interaction, etc
ModelingComponents:
add UGeometrySelectionEditCommand/Arguments, this is a UInteractiveCommand that uses a FGeometrySelection as an argument
add UGeometrySelectionManager::CanExecuteSelectionCommand() and ExecuteSelectionCommand()
MeshModelingTools:
add UDeleteGeometrySelectionCommand, deletes selected mesh geometry by converting input selection to list of triangles
ModelingToolsEditorMode:
add Delete command to ModelingMode and UI. ModelingToolsEditorMode currently is keeping active command set alive via new UModelingToolsEditorMode::ModelingModeCommands member.

GeometrySelection.h/cpp: FGeometrySelection, FGeometrySelectionEditor, representation and manipulation of a generic element-level selection, stored as a set of uint64. Editor makes changes to Selection while tracking deltas.
GeometrySelectionUtil.h/cpp: utility and helper functions for editing/processing a mesh+selection
GeometrySelector.h: FGeometryIdentifier type used to identify target objects with element-level selection support. IGeometrySelector interface that defines API for element selection for a type of target object. Factory type for spawing instances. IGeometrySelectionTransformer interface that defines API for element-level transformation
GeometrySelectionManager.h/cpp: UGeometrySelectionManager that maintains set of 'active targets' with associated Selector, Selection, and SelectionEditor, and provides high-level API for creating and querying element selections, 3D transforms of selections, selection undo/redo, and (currently) limited debug rendering
GeometrySelectionChanges.h/cpp: FChange types for element selection changes
DynamicMeshSelector.h/cpp: implementation of IGeometrySelector for UDynamicMesh/Component
