# Build a Jigsaw puzzle for Lasercutting.
# User defines:
# - dimensions,
# - number of pieces in X and Y,
# - notch size,
# - random amount of perturbation for uniqueness,
# - border and rounding for border and inner corners
# - random or random seed for repeats
### 0.1 make basic jigsaw for lasercut - March 2011
### 0.2 add random seed so repeatable, add pieces for manual booleans - May 2011
### 0.3 add some no-knob edges - June 2019
### Todo
# add option to cut pieces:
# - taking two rows(cols) at a time - reverse the second one and concat on end - add z to close
# - taking a row and a col - do intersect = piece.
