GetMatchList
public BackendReturnObject GetMatchList();
Description
Look up the information of matching cards created in BACKND Console.
inDate, name, and type of the match, as well as all established time values are returned.  
Example
Synchronous
Backend.Match.GetMatchList();
Asynchronous
Backend.Match.GetMatchList(callback => {
  // Post-process
});
SendQueue
SendQueue.Enqueue(Backend.Match.GetMatchList, callback => {
  // Post-process
});
Return cases
