* Logging
|
|
* -------
|
|
* Servers and clients may contain a logger. Every logger needs to implement the
|
|
* `UA_Logger` signature. An example logger that writes to stdout is provided in
|
|
* the plugins folder.
|
|
*
|
|
* Every log-message consists of a log-level, a log-category and a string
|
|
* message content. The timestamp of the log-message is created within the
|
|
* logger.
