Note that the range of values of the index depends on the the connectivity used by the <a class="el" href="namespaceitk_1_1watershed.html">watershed</a> segmentation algorithm. If the WS algorithm uses city-block style connectivity (4-connectivity in 2D, 6-connectivity in 3D, etc) this could actually be a boolean value indicating inward or outward flow since there is only one valid neighbor to reference. For extensibility to other connectivities, this flow value can be used to index a number of different neighbors.
