This Meteor smart package provides extendPublish helper. You should pass to it a function which receives
name, func, options and returns an array of potentially new values to be passed to Meteor.publish.
After extendPublish has been called (potentially multiple times), every call to Meteor.publish will first
call this function (or functions) instead, before passing arguments to core Meteor.publish.
Server side only.
