Mission avoids consciously using clear and handy structure of Chore class,
for to leave space for innovation and to find different solutions for ops.
Mission handles acts below -app level, but above chore.
Mission can include many chores. 7 Chores are build by default.
TODO Mission has 31 public members !!
TESTED: when extending BaseStruct: Too many arguments in constructor.
Generic list to keep all missions.
In case for handling other, super- or sub-missions; code something more.
