Add UMeshWireframeComponent, this is a component that renders mesh edges as lines, with line color/thickness varying depending on line type. Accesses mesh via an API so client does not have to handle iterations/etc (derived from LineSetComponent).
Add UMeshElementsVisualizer, subclass of UPreviewGeometry that displays mesh information (currently using UMeshWireframeComponent)
Small optimization to ULineSetComponent to avoid calling MarkRenderStateDirty() for each line when adding many lines.
