+/**
+ * Holds a log message and provides convenience methods to read the information.
+ *
+ * The ezclogMessage class is used for subtracting the information from the message
+ * parameter from {@link trigger_error()}. See the {@link ezcLog::logHandler} for 
+ * more information. 
+ *
+ * The message formats that can be parsed are: 
+ * <pre>
+ * [ source, category ] Message 
+ * </pre>
+ *
+ * When one name is given between the brackets, the category will be set and the message has a default source:
+ * <pre>
+ * [ category ] Message
+ * </pre>
+ *
+ * Without any names between the brackets, the default category and source are used:
+ * <pre>
+ * Message
+ * </pre>
+ * 
+ * The following properties are set after construction or after calling {@link parseMessage()}:
+ * - message, contains the message without extra the additional information.
+ * - source, contains either the default source or the source set in the incoming message.
+ * - category, contains either the default category or the category set in the incoming message.
+ * - severity, severity of the error. Which is ezcLog::NOTICE, ezcLog::WARNING, or ezcLog::ERROR.
