+ * Validation to add an address to a system
+ * o = System::class
+ *
+ * @note This validation only expects to be used with POST
+ * Variables:
+ * + "action" => "node"		// type of address being created
+ * + "zone_id" => "2"
+ * + "region_id" => "21"
+ * + "host_id" => "3"
+ * + "hub_id" => null
+ * + "node_id" => "9999"
+ * + "point_id" => "0"
+ * + "region_id_new" => null	// creating a new region id
+ * + "host_id_new" => null		// creating a new host id
+ * + "node_id_new" => null		// creating a new node id
+ * + "hub" => "0"
+ * + "security" => "9"
+ *
+ * Rules:
+ * - ZC is z:0/0.0 - region,node,point must be zero
+ *   ZC is identified when region_id,host_id,node_id and point_id === 0
+ * - RC is z:r/0.0 - region is non-zero, host_id = region_id, node,point must be zero.
+ *   RC is identified when region_id === host_id and, node_id and point_id === 0
+ * - NC is z:h/0.0 (r=r, r!=h, h!=z) [parent where z:r/0 and h=r, n=0]
+ *   NC is identified when region_id !== host_id and, node_id and point_id === 0,
+ * - HC is z:h/n.0 (r=r) [parent pointed by hub_id AND validate by z:h/0 is the hub_id]
+ *   HC is a normal node with, but has children pointing to it with hub_id
+ * - NN is z:h/n.0 when point_id === 0
+ *   A normal node where node_id !== 0, it may or may not have a hub_id
+ * - PT is z:h/n.p where point_id !== 0
+ *   PT is identified when point_id !== 0;
