Overridden from UInteractiveToolActivity

	Name	Description
bool	CanAccept()	If true, calling End with EToolShutdownType::Accept will result in a valid completion of the activity.
bool	CanStart()	Check whether a Start() call will result in a success.
EToolActivit...	End ( EToolShutdownType )	Force an end to the activity.
bool	IsRunning()	Check whether the activity is running (though the tool can just check the result of Start() itself).
void	Shutdown ( EToolShutdownType ShutdownType )	Should be called during a tool's Shutdown()Should be called during a tool's Shutdown()
EToolActivit...	Start()	Attempt to start the activity.

Overridden from UInteractionMechanic

	Name	Description
void	Render ( IToolsContextRenderAPI* Render... )	If the activity is running, should be called from the tool's Render()
void	Setup ( UInteractiveTool* ParentTool )	IInteractiveToolActivity.
void	Tick ( float DeltaTime )	If the activity is running, should be called from the tool's OnTick()
