I have been thinking of various ways to populate my collection classes
with its children.


1) I could create the .Add function of the collection class to accept a
child object as an argument, which then adds the child to the collection.

2) I could create the .Add function of the collection class to not
accept any arguments, and to just return a new child object


I do not know when one method would be preferred over the other. Can
anyone help? Thanks!
