When performing an upstream or downstream trace, flow direction for the subnetwork is first determined and then
features upstream or downstream to the starting points are returned. In some cases, a specific flow direction
cannot be determined, such as scenarios with loops. In cases such as this, the flow is known as indeterminate.
By default, features with indeterminate flow are included in the trace results when this property is set to true.
If this property is set to false, features with indeterminate flow will stop traversability and will not be
included in the trace results.
