@chparent'ing the rooms to the test room has a similar affect as if you had
just created a new child of the test room. It now has all the verbs and
properties of the test room. It's properties are at this point `inherited'
the parent (similar to verbs). Thus changing the property on the parent
changes it on the child. *IF* you @set the properties of the child, they
will then be stored locally on the child object, and will no longer reference
the parent at all (even if you @set them to the same value). So until a
property is altered locally, it is just inherited from the parent. Once there
is an alteration that inheritance is broken forever.
