Remarks
Often on maps plotted symbols and text overlap each other. This routine accepts of VV of locations and returns a new set of locations offset from the originals, and guaranteed not to overlap, given the size of the original symbols. The returned offset X, Y locations are offset from the original locations by the minimum of a) the input offset, b) the input symbol X or Y size. This is to ensure that the original location is never covered by the offset symbol. In addition, the offset symbol is never place directly below the original location, to make it easier to draw a connecting line. Care should be taken when choosing the symbol size, because if the point density is too high, all the points will get pushed to the outside edge and your plot will look like a hedgehog (it also takes a lot longer!).
