Create a pre-made beam line element (because it's a non-continuous beam line) for a bridge section between two curvilinear volumes. Can cope if nextElement == end. numberOfUniqueComponents will be incremented if a new accelerator component is required. This is only done if the two components that are being bridged have angled faces. beamlineIndex is the index the element will have in the non-continuous beam line; the indices should be continuous. crRadius controls the radius of the component.

	)

private

Create a curvilinear element for a beam line that represents the curvilinear coordinates between startElement and finishElement. This creates a BDSSimpleComponent first then wraps it in a pre-made BDSBeamlineElement. This must ONLY be used for a range of elements with the same tilt for the correct coordinate frame to be produced. The tilt is taken from the first element and assumed to be the same for all. The index is the index it'l have in the curvilinear beam line.
