 /**
 36  
  * This action doPerforms an Access Control List and places it into
 37  
  * the RunData object, so it is easily available to modules.  The ACL
 38  
  * is also placed into the session.  Modules can null out the ACL to
 39  
  * force it to be rebuilt based on more information.
 40  
  *
 41  
  * <p>
 42  
  *
 43  
  * Turbine uses a User-Role-Permission arrangement for access control.
 44  
  * Users are assigned Roles.  Roles are assigned Permissions.  Turbine
 45  
  * modules then check the Permission required for an action or
 46  
  * information with the set of Permissions currently associated with
 47  
  * the session (which are dependent on the user associated with the
 48  
  * session.)
 49  
  *
 50  
  * <p>
 51  
  *
 52  
  * The criteria for assigning Roles/Permissions is application
 53  
  * dependent, in some cases an application may change a User's Roles
 54  
  * during the session.  To achieve flexibility, the ACL takes an
 55  
  * Object parameter, which the application can use to doPerform the
 56  
  * ACL.
 57  
  *
 58  
  * <p>
 59  
  *
 60  
  * This action is special in that it should only be executed by the
 61  
  * Turbine servlet.
