Calculates default vertex locations for the current graph by using the current layout, 
excluding those vertices in the given <i>ignore</i> set.  The graph, 
layout and vertices will be unaltered.

@param verticesToIgnore The set of vertices which should be excluded from the layout process
@return The mapping of all arranged vertices to their respective locations
