anything against adding this @jmwright ?

[adam-urbanczyk]

It is a simple README change, so I'm going ahead with the merge.

[jmwright]

@adam-urbanczyk Sorry, been AFK for a lot of the day. I don't really understand what the purpose of the DOI badge is, and I don't get why it seems to be pointing to CQ-editor.

[adam-urbanczyk]

Yes, fixed in #412 ... Digital Object Identifier can be used to cite CadQuery in scientific publications. So far I found two. They point to the old repo unfortunately.

[jmwright]

Ah, ok. Got it. Thanks for adding this.
