Detailed Description

The abstraction of something that can be done. It can be an ordinary CallBack, a static function (must return bool) or a TaskFunction on a CallBackerinheriting class, or a Task. The three examples are shown below.

mExpClass(Basic) MyClass : public CallBacker
{
    void            normalCallBack(CallBacker*);
    bool            taskFunction();
    static bool     staticFunc();
};

Calls to normalCallBack and task functions can be invoked as:

Threads::WorkManager::twm().addWork(
            Work(mCB(this,MyClass,normalCallBack) ) );

or

Threads::WorkManager::twm().addWork( mWMT(this,MyClass,taskFunction));

or

Threads::WorkManager::twm().addWork( Work( &MyClass::staticFunc) );

You can also add Tasks, with the option that they may be deleted when the work is done, or if there is an error.
