UPSTREAM

Gets a list of references to all shapes FROM which a line has been drawn TO the current shape

For example, for two shapes A and B, if a line is drawn from A to B, then A is upstream of B. If another shape C is added, and a line is drawn from B to C, then B is upstream of C. If another shape D is added, and a line is drawn from D to B, then D is upstream of B.

TRICKY: The directions of the arrows have no bearing on this.
