This class implements a small mutable state object which keeps track of
which wells have been automatically closed by the simulator through the
WTEST mechanism.
The default behavior of the container is to manage *closed* wells, but
since the counter mechanism for the maximum number of opening attempts
should maintain the same counter through open/close events we need to
manage the well object also after they have been opened up again.

The purpose of this container is to manage explicitly *closed wells*,
since the class has no relation to the set of of wells defined in the
Schedule section the concept of open wells and totally unknown wells is
slightly murky:
well_is_closed("UNKOWN_WELL") -> false
This implies that we have not explicitly closed a well with name
'UNKNOWN_WELL', but since we do not know whether the well is at all
defined it does not make sense to extrapolate to:
well_is_open("UNKNOWN_WELL") -> true.
That is the reason we do not have any xxx_is_open() predicates.
