This is a test script modification of the BooleanDifference command, which permits the user to select a Chunk number,
to do the subtractions in batches. Tested with the BottleFeedArray2 script, the Booleans go slower and slower with increased bottle count.

Similar slowing occurs with batches, but with a chunk size of 1 or 2 or 5 or 10, some activity may be seen, and a problem area located,
or worked around. For a rotating oval bottle, some orientations seem to be harder to BooleanDifference.
Selection order seems to be a factor, as well as the number of bottles, with smaller slivers.

Please backup .3dm before testing.

With Barry's screw and oval bottle specs, for 160 bottle station, the BooleanDiff subtraction was accomplished, with ChunkSide of 1 or 2 or 3,
with sequential selection of a few bottles. Occasionally I was able to crash MoI, but most of the time the test script worked ok.
