Delete slots add, main + Add slots lock, cv, behavior

add() and main() functions were removed from the class and made into individual methods.

Consequently lock, cv and behavior() which would be required by actor.add() and
actor.main() methods are brought into the actor class for access by the methods.

Also get-add and consequent logic is put into actor.send() method
