API
Logger(namespace, eventSink)
Create a logger with the specified namespace (optional) and the specified event sink (optional). Returns an object with these methods:
[silly|debug|verbose|info|warn|error(message, err)
Log a message of the specified level with optional error
on(event, handler)
Subscribes to events from the logger.
withNamespace(namespace, separator)
Creates a child logger with the specified namespace. If the current logger has a namespace, the new namespace is created to look like 'old:new'. Use the separator
parameter to specify a different separator than ':'. If separator === false
, then the new namespace will not include the old.
