-Provides the ability to execute one or more arbitrary tasks in a multithreaded manner. Generally, you can use
-the singleton <a ext:cls="Ext.TaskMgr" href="output/Ext.TaskMgr.html">Ext.TaskMgr</a> instead, but if needed, you can create separate instances of TaskRunner. Any
-number of separate tasks can be started at any time and will run independently of each other. Example usage:
