 By default the path is a closed loop. An open loop can be specified by specifying `open=true`, and in that case the start and end points are not connected, leaving the loop open.

 the position with that number. Alternatively `twist` can be a list of boolean values with a boolean for each position; the belt will then twist after
 the position that have a `true` value in the `twist` list. If the path is specified with pulley/idler types, then you can use `auto_twist=true`; in
