Beating the apps script custom function 30 second time limit. Alpha? Beta? :P

30 second beat code

//David Sottimano
//@dsottimano on Twitter for feedback please!

//lets set up our queue runner to run every 1 minutes

//if queue param is true, we ship off the function details along with where it was called to the propertyservice
