renamed to AtomicMonoCollection
some replacements Complements to Complements2; deleted UnaryComplements
renamed AtomicUnaryComplements to AtomicComplementsMono, etc.
Note: this class is a very light implementation of a 1-element
Complement container based on an essence object.
It avoids extending AtomicMonoCollection, thus reducing by 1 reference
the memory consumption. The price is that it must implement all the
Collection methods explicitely (only stumps are present now)
deleted AbstractComplement, etc.
