stock to leave: offset-cutters

[GoogleCodeExporter]

Some ideas for this new feature:

One way of specifying a stock-to-leave(let's call it s) value for machining
operations is to calculate the toolpaths using an offset-cutter, which is
larger than the original cutter by the stock-to-leave value s.

This could be done so that every operation/algorithm is able to take a
stock-to-leave value s, and when the machining operations are called the
actual computations are done using the offset cutter.

Some examples of offset-cutters:
BallCutter(d) offset by s ->  BallCutter(d+2s)
CylCutter(d) offset by s -> BullCutter( d+2s, s)
BullCutter(d,r) offset by s -> BullCutter( d+2s, r+s)

if and when the cutting-simulation is completed it will be possible to
probe the stock-model and the original STL drive-surface and check that the
programmed stock-to-leave value is actually achieved.

this is now implemented partly as of r230

it should work for the basic cutter shapes (Cylinder, Ball, Bull, Cone).
But not yet for composite cutters...

/scripts/offsetCutter_test.py     shows how this works.

this feature is now included for most if not all cutters. closing issue.
