"""

This module defines ActionGroup, ActionEnvelope, and ActionBundle -- classes that together
|
|
represent the result of applying a UserAction to a document.
|
|
|
|
In general, UserActions refer to logical actions performed by the user. DocActions are the
|
|
individual steps to which UserActions translate.
|
|
|
|
A list of UserActions applied together translates to multiple DocActions, packaged into an
|
|
ActionGroup. In a separate step, this ActionGroup is split up according to ACL rules into and
|
|
ActionBundle consisting of ActionEnvelopes, each containing a smaller set of actions associated
|
|
with the set of recipients who should receive them.
