Returns a handle to the instance representing the head of design tree within the Geometry Kernel.
If no design tree is created yet it will be created on-the-fly.
Note: the STEP Engine uses one or more models within the Geometry Kernel to generate design trees
within the Geometry Kernel. All Geometry Kernel calls can be called with the STEP instance handle also,
however most correct would be to get and use the Geometry Kernel handle.
