class	TGo4TaskManager

Detailed Description

This class is responsible for the interconnection of two tasks: provided are three communication channels (data, command, status), one thread runnable is acting on each transport channel (e.g. socket); one queue (buffer) is assigned to each channel depending on client or server mode of the task handler, the threads get objects from transporl and put them into the queue, or vice versa. (servertask sends commands, but receives data and status objects) taskhander is named such that it can be found in a list (i.e. task manager) by the server task which may serve more than one client tasks
