/**
* Setup the logging system
*
* If you want to use the built-in logging system, you need to
* call this function at least once, in order to load the logging logic.
* You might customize logging properties by providing custom
* arguments. If you don't, default values are used. (see below)
*
* You can check if the logging has been loaded:
* if(defined('AB_LOG'))
* print 'Logging is loaded';
*
* <br><b>Default values</b>
* - <samp>$dir = dirname(ini_get('error_log'))</samp> or /tmp if error_log is not set or points to syslog.
* - <samp>$defaultLogfile = 'web'</samp>
* - <samp>$level = (error_reporting() & E_NOTICE ? 1:0) + (error_reporting() & E_WARNING ? 1:0) + (error_reporting() & E_ERROR ? 1:0);</samp>
*
* <br><b>Value of default Level</b>
* - Level is 3 (everything) if E_NOTICE, E_WARNING and E_ERROR is included in error reporting. (default)
* - Level is 2 (warnings and errors) if E_WARNING and E_ERROR is included in error reporting, but not E_NOTICE.
* - Level is 1 (only errors) if only E_ERROR is included in error reporting
* - Level is 0 (nothing) if neither E_NOTICE, E_WARNING or E_ERROR is included in error reporting.
*
* @param string NAME of log file. Correct: "my_log", Wrong: "my_log.log". ".log"
* is prepended to name and written to $dir. (null = use defaults)
* @param string Absoulte path to a directory in which the web server can create
* files. (null = use defaults)
* @param int Decides which messages acctually get written. 0 = none,
* 1 = only log_error, 2 = log_error and log_warn, 3+ = everything.
* (null = use defaults)
* @param string
* @param bool
* @return void
* @see log_info()
* @see log_warn()
