  * Adds a Role having an identifier unique to the registry

  * The $parents parameter may be a reference to, or the string identifier for,
  * a Role existing in the registry, or $parents may be passed as an array of
  * these - mixing string identifiers and objects is ok - to indicate the Roles
  * from which the newly added Role will directly inherit.
  *
  * In order to resolve potential ambiguities with conflicting rules inherited
  * from different parents, the most recently added parent takes precedence over
  * parents that were previously added. In other words, the first parent added
  * will have the least priority, and the last parent added will have the
  * highest priority.
