 GlideQuery's can greatly simplify extracting information from queries, especially when dot walking.
 
-This query retrieves a user's roles, and returns an array of objects with the the role's display
-value, the role's active status, the user's display value, and the user's email.  Adding more
-fields is trivial with this format, and the query stream is very easy to follow.
+This code has been updated to simplify the function to return an array of roles for the given user.  Shows the use of GlideQuery and .reduce() in place of .toArray().
