Refactor most of FDynamicMeshSelector into FDynamicMeshSelectorBase, FDynamicMeshSelector is now a subclass.
Move the DynamicMeshTransformer from cpp to FBasicDynamicMeshSelectionTransformer in header.
Add FVolumeSelector and FStaticMeshSelector which are derived from FBaseDynamicMeshSelector.
Add ability to filter selection queries/edits by TopologyID in FGeometrySelectionEditor. This is necesary for polygroup and polygroup-edge selections as their encoding includes an arbitrary TriangleID paired w/ the TopologyID.
UGeometrySelectionManager now manages this TopologyID filtering on selection editors it creates/updates
Add concept of "Tracked" selection changes to UGeometrySelectionManager, allows a single selection FChange to be constructed incrementally, eg like with a brush. Add a variant of raycast-selection-update that can be run inside a tracked change.

Introduced FGeometrySelectionHitQueryConfig (GeometrySelection.h), this provides information about the active selection mode. FGeometrySelectionEditor now tracks active FGeometrySelectionHitQueryConfig.
IGeometrySelector hit-testing/processing functions now take a struct FWorldRayQueryInfo that combines a FRay3d with FViewCameraState, to allow for (eg) snapping wrt the active camera/etc
Added FGeometrySelectionPreview, this is a utility subclass of FGeometrySelectionEditor that is used for selection-preview highlighting, relative to a base FGeometrySelectionEditor
Added IGeometrySelector::GetSelectionPreviewForRaycast() which is used to accumulate a preview of what might be selected in a FGeometrySelectionPreview. AccumulateSelectionElements() can also now accumulate 'preview' geometry, and FDynamicMeshSelector uses this to provide the edge-loop of a facegroup for it's preview (as providing all triangles is too expensive for hover highlighting on hires meshes).
Added support for hover-highlighting mechanic in UGeometrySelectionManager and UModelingSelectionInteraction
FDynamicMeshSelector now creates a GroupEdgeSegmentTree for polygroup edges. This allows for better selection interaction, eg no dependency on the edge-adjacent triangles.
Added AreSelectionsIdentical() function in GeometrySelectionUtil.h

GeometryScriptSelectionTypes.h:
New type FGeometryScriptMeshSelection stores Vertex, Triangle, and Polygroup selections. Currently internally represented as a TSharedPtr<FGeometrySelection>, however this is not exposed to BP at all. FGeometryScriptMeshSelection is an opaque object w/ no exposed properties, and it's contents cannot be serialized, ie it is only usable as temporary data during active GeometryScript computations.
MeshSelectionFunctions.h: library of functions for creating/manipulating mesh selections
CreateSelectAllMeshSelection - create a Mesh Selection for all elements of Mesh
ConvertMeshSelection - convert a Mesh Selection to a different type
CombineMeshSelections - combine two Mesh Selections using set operations (union, difference, intersection)
ConvertIndexArrayToMeshSelection / ConvertIndexSetToMeshSelection - convert TArray<int> / TSet<int> to a Mesh Selection
ConvertIndexSetToMeshSelection - convert a Mesh Selection to TArray<int>
ConvertIndexListToMeshSelection / ConvertMeshSelectionToIndexList - convert between an Index List and a Mesh Selection
SelectMeshElementsInBox, SelectMeshElementsInSphere, SelectMeshElementsWithPlane - create a Mesh Selection of all elements "inside" a geometric element
SelectMeshElementsByNormalAngle - create a Mesh Selection of all elements based on normal vector direction
SelectMeshElementsInsideMesh - create a Mesh Selection of all elements inside another mesh (with optional extra shell thickness)
ExpandMeshSelectionToConnected - expand a Mesh Selection to Connected regions (various connectivity criteria)
GetMeshSelectionInfo - get the type and size of a Mesh Selection
DebugPrintMeshSelection - print a Mesh Selection to the output log
MeshSelectionQueryFunctions.h: library of functions for doing mesh queries based on a selection
GetMeshSelectionBoundingBox - get the bounding box of a Mesh Selection
GetMeshSelectionBoundaryLoops - get the boundary loops (indices and 3D polylines) of a Mesh Selection
