 * Loads a map list to an ADT Array.

 * A map list is a list of maps from a file.  SourceMod allows easy configuration of

 * name and a file (for example, "rtv" => "rtv.cfg"), or a name and a redirection 

 * (for example, "rtv" => "default").  This native will read a map list entry, 

 * cache the file, and return the list of maps it holds.  

 *

 * Serial change numbers are used to identify if a map list has changed.  Thus, if 

 * you pass a serial change number and it's equal to what SourceMod currently knows 

 * about the map list, then SourceMod won't reparse the file.

 *

 * or the contents of arrays returned to other plugins.

 *						array will be created.  The blocksize should be at least 16; 

 *						otherwise results may be truncated.  Items are added to the array 

 *						as strings.  The array is never checked for duplicates, and it is 

 *						not read beforehand.  Only the serial number is used to detect 

 *						changes.

 * @param serial		Serial number to identify last known map list change.  If -1, the 

 *						the value will not be checked.  If the map list has since changed, 

 *						the serial is updated (even if -1 was passed).  If there is an error 

 *						finding a valid maplist, then the serial is set to -1.

 * @param str			Config name, or "default" for the default map list.  Config names 

 *						should be somewhat descriptive.  For example, the admin menu uses 

 *						a config name of "admin menu".  The list names can be configured 

 *						by users in addons/sourcemod/configs/maplists.cfg.

 * @param flags			MAPLIST_FLAG flags.

 * @return				On failure:

 *						 INVALID_HANDLE is returned, the serial is set to -1, and the input 

 *						 array (if any) is left unchanged.

 *						On no change:

 						 INVALID_HANDLE is returned, the serial is unchanged, and the input 

 						 array (if any) is left unchanged.

 *						On success:

 *						 A valid array Handle is returned, containing at least one map string.  

 *						 If an array was passed, the return value is equal to the passed Array
