Optional "info" object for each entry #4

It would be quite practical to have the option to maintain an "additional information" list where, for example, the user could store the respective solutions.

nda = moarchiving.BiobjectiveNondominatedSortedList()
nda.add(fun2(x), info=x)
nda.add(fun2(xa), info={'x': xa, 'note': 'xa seems to rock'})
nda.add(fun2(xb))
assert nda.info is None or len(nda) == len(nda.info)
print(nda.info)  # nda has an info property
[[0, 1, 2], {'x': [1, 2, 3], 'note': 'xa seems to rock'}, None]

Methods that need to be modified are

The list can be created only when an optional info argument is used for the first time to avoid always maintaining an info list of None elements.

Do you think it could be useful to also have the possibility to add a list of infos together with the list of f values when initializing the object? In 3 dimensions for example, adding points to the archive at initialization is much faster than adding them separately after.

Makes perfectly sense to me.
