Running modeler under OSX 10.15

[Aristedes Maniatis]

OSX 10.15 makes it incrementally harder to run an unsigned application. 
No longer do you get a dialog asking you to approve this suspicous 
application. But you can do this in the terminal if you can't find the 
place in System preferences to do it:

xattr -dr com.apple.quarantine /Applications/CayenneModeler.app


Not sure if the Apache Foundation has an Apple dev account which would 
allow us to sign the app.
