Describe the enhancement requested

The Grouper API could be useful for functionality such as Pivot. However, it lacks the following functionality:

  1. ability to prepopulate the grouper without necessarily returning group ids
  2. ability to lookup keys without generating new groups for keys that haven't been encountered yet
