 // The ExtensionsQuotaService uses heuristics to limit abusive requests
 // made by extensions.  In this model 'items' (e.g individual bookmarks) are
 // represented by a 'Bucket' that holds state for that item for one single
 // interval of time.  The interval of time is defined as 'how long we need to
 // watch an item (for a particular heuristic) before making a decision about
 // quota violations'.  A heuristic is two functions: one mapping input
 // arguments to a unique Bucket (the BucketMapper), and another to determine
 // if a new request involving such an item at a given time is a violation.
