+/**
+ * \brief holds a vector of std::pair of Ptr<Ccnx> and face index.
+ *
+ * Typically ns-3 CcnxFaces are installed on devices using an Ccnx address
+ * helper.  The helper's Assign() method takes a NetDeviceContainer which holds 
+ * some number of Ptr<NetDevice>.  For each of the NetDevices in the 
+ * NetDeviceContainer the helper will find the associated Ptr<Node> and
+ * Ptr<Ccnx>.  It makes sure that an face exists on the node for the 
+ * device and then adds an CcnxAddress according to the address helper settings
+ * (incrementing the CcnxAddress somehow as it goes).  The helper then converts
+ * the Ptr<Ccnx> and the face index to a std::pair and adds them to a 
+ * container -- a container of this type.
+ *
+ * The point is then to be able to implicitly associate an index into the 
+ * original NetDeviceContainer (that identifies a particular net device) with
+ * an identical index into the CcnxFaceContainer that has a std::pair with
+ * the Ptr<Ccnx> and face index you need to play with the face.
+ *
+ * @see CcnxAddressHelper
