Specifies whether position constraints are applied top-down by setup rank number vs. bottom-up by strategy number
True - apply constraints top-down
False - apply constraints bottom-up (default)
TopDownMode was introduced in RealTest 2.0.26.
If this setting is not specified or is set to False, constraints are applied "bottom-up" (one strategy at a time) as before.
When TopDownMode is True, the new approach is used.
