Title: Instructions for using an array with scope

Added some documentation for specifying scope using an array. We ran into a problem using an array because we were using symbols without the appended _id. It was not clear from the documentation that when using an array, the full column names need to be specified, and that the _id will NOT be appended as happens when a single symbol is used for the scope.
