class TQMultiObservable: public TQObservable


 TQMultiObservable

 The TQMultiObservable is a sort of meta-observable that will act
 upon other observables and combine their respective
 output. Creation of such an observable can be triggered by
 prepending 'Multi:' to any expression, or by using brackets [...]
 in such a way that they enclose an unquoted string. Each segment
 enclosed in such brackets will be interpreted as the name of some
 other observable, which will be evaluated and inserted in this
 expression at runtime. Please note that TQMultiObservable does not
 provide any direct data access, which means that you shall not use
 any branch names in this expression directly, but only other
 observable names.
