 * A ChannelMonitor handles chain events (blocks connected and disconnected) and generates
 * on-chain transactions to ensure no loss of funds occurs.
 * 
 * You MUST ensure that no ChannelMonitors for a given channel anywhere contain out-of-date
 * information and are actively monitoring the chain.
 * 
 * Pending Events or updated HTLCs which have not yet been read out by
 * get_and_clear_pending_monitor_events or get_and_clear_pending_events are serialized to disk and
 * reloaded at deserialize-time. Thus, you must ensure that, when handling events, all events
 * gotten are fully handled before re-serializing the new state.
 * 
 * Note that the deserializer is only implemented for (BlockHash, ChannelMonitor), which
 * tells you the last block hash which was block_connect()ed. You MUST rescan any blocks along
 * the \"reorg path\" (ie disconnecting blocks until you find a common ancestor from both the
 * returned block hash and the the current chain and then reconnecting blocks to get to the
 * best chain) upon deserializing the object!
