Generates Inkscape SVG file containing box components needed to
laser cut a tabbed construction box taking kerf and clearance into account
CNC (laser/mill) cut a box with tabbed joints taking kerf and clearance into account

Changelog:
19/12/2014 Paul Hutchison:
@ -35,6 +35,16 @@ v0.99 - 2020-06-01 by Paul Hutchison
- Fixed divider issues with Rotate Symmetric
- Made individual panels and their keyholes/slots grouped
v1.0 - 2020-06-17 by Paul Hutchison
- Removed clearance parameter, as this was just subtracted from kerf - pointless?
- Corrected kerf adjustments for overall box size and divider keyholes
- Added dogbone cuts: CNC mills now supported!
- Fix for floor/ceiling divider key issue (#17)
- Increased max dividers to 20 (#35)
v1.1 - 2021-08-09 by Paul Hutchison
- Fixed for current Inkscape release version 1.1 - thanks to PR from https://github.com/roastedneutrons
