A molecular system can be defined by a set of items, not only one.
This means that all methods should be able to work with a list of items, not just one.
This way, the possibility to have an item for the topology, a second item for the coordinates, and a third item for the box, i.e., requires auxiliary methods to deal with it.
In addition, this has to be documented as something implicit in the philosophy of MolSysMT.
