/******
 *
 * GxsCircles are used to limit the spread of Gxs Groups and Messages.
 *
 * This is done via GxsCircle parameters in GroupMetaData:
 *      mCircleType (ALL, External, Internal).
 *      mCircleId.
 *
 * The Circle Group contains the definition of who is allowed access to the Group.
 * and GXS asks this service before forwarding any data.
 *
 * The CircleGroup contains:
 *      list of GxsId's
 *      list of GxsCircleId's (subcircles also allowed).
 *
 * This service runs a background task to transform the CircleGroups
 * into a list of friends/peers who are allowed access.
 * These results are cached to provide GXS with quick access to the information. 
 * This involves:
 *      - fetching the GroupData via GXS.
 *      - querying the list of GxsId to see if they are known.
 *		(NB: this will cause caching of GxsId in p3IdService.
 *      - recursively loading subcircles to complete Circle definition.
 *      - saving the result into Cache.
 *
 * For Phase 1, we will only use the list of GxsIds. No subcircles will be allowed.
 * Recursively determining membership via sub-circles is complex and needs more thought.
 * The data-types for the full system, however, will be in-place.
