Subject: Use single chars for set operators
X-Git-Url: https://git.ljiriste.work/?a=commitdiff_plain;h=98142ca9e16b4e5a33573b35bd4aac48447b0bb3;p=SetSCAD.git

Use single chars for set operators

Using letters for operators may prove to be a silly choice but I tried
to use those that look somewhat like the correct symbols.
