59// instance. The MF-Task is added to the tasklist in front of the MContinue
60// instance and also automatically deleted, eg.
61// MContinue cont("MHillas.fSize<20");

64// in the tasklist.

66// will search for the filter and if it isn't found in the tasklist it
67// is added to the tasklist in front of MContinue.
