// Implementation notes.
// NetworkLibraryImpl manages a series of classes that describe network devices
// and services:
//
// NetworkDevice: e.g. ethernet, wifi modem, cellular modem
// device_map_: canonical map<path, NetworkDevice*> for devices
//
// Network: a network service ("network").
// network_map_: canonical map<path, Network*> for all visible networks.
// EthernetNetwork
// ethernet_: EthernetNetwork* to the active ethernet network in network_map_.
// WirelessNetwork: a WiFi or Cellular Network.
// WifiNetwork
// active_wifi_: WifiNetwork* to the active wifi network in network_map_.
// wifi_networks_: ordered vector of WifiNetwork* entries in network_map_,
// in descending order of importance.
// CellularNetwork
// active_cellular_: Cellular version of wifi_.
// cellular_networks_: Cellular version of wifi_.
// network_unique_id_map_: map<unique_id, Network*> for all visible networks.
// remembered_network_map_: a canonical map<path, Network*> for all networks
// remembered in the active Profile ("favorites").
// remembered_network_unique_id_map_: map<unique_id, Network*> for all
// remembered networks.
// remembered_wifi_networks_: ordered vector of WifiNetwork* entries in
// remembered_network_map_, in descending order of preference.
// remembered_virtual_networks_: ordered vector of VirtualNetwork* entries in
// remembered_network_map_, in descending order of preference.
//
// network_manager_monitor_: a handle to the libcros network Manager handler.
// NetworkManagerStatusChanged: This handles all messages from the Manager.
// Messages are parsed here and the appropriate updates are then requested.
//
// UpdateNetworkServiceList: This is the primary Manager handler. It handles
// the "Services" message which list all visible networks. The handler
// rebuilds the network lists without destroying existing Network structures,
// then requests neccessary updates to be fetched asynchronously from
// libcros (RequestNetworkServiceProperties).
//
// TODO(stevenjb): Document cellular data plan handlers.
//
// AddNetworkObserver: Adds an observer for a specific network.
// UpdateNetworkStatus: This handles changes to a monitored service, typically
// changes to transient states like Strength. (Note: also updates State).
//
// AddNetworkDeviceObserver: Adds an observer for a specific device.
// Will be called on any device property change.
// UpdateNetworkDeviceStatus: Handles changes to a monitored device, like
// SIM lock state and updates device state.
//
// All *Pin(...) methods use internal callback that would update cellular
// device state once async call is completed and notify all device observers.
