21  * <p>
22  * Represents an association between user, role and group: when a user is placed
23  * into a group, group roles are assigned to him; so, for each role in group
24  * a triad is created: &lt;user, role, group&gt;, where <em>user</em> is a user
25  * which is placed to a group, <em>role</em> is role which belongs to a group,
26  * and <em>group</em> is a group to which user is placed. Such triad is
27  * represented with this class.
28  * </p>
29  * <p>
30  * When a role is assigned directly to user, not through group, third component
31  * is <code>null</code>.
