This function simply does some background work that each of
"'>downLogIZs" and
"'>standingTreeIZs" subclasses have in common for
object creation. It is not meant to be called as a general
function by the casual user.
izContainer(object, ...)the one signature object, a list.
Just gobbled for now.
Currently returns just the overall bounding box of all the objects in
the list. However, it may acquire more functionality later on.
See the returned value below. Note that this is pre-object
creation, so it does not make sense to have a bbox method to
calculate the overall bounding box. A bbox method based on a
list object is also out of the question because the list could
contain anything; in this routine the list passed must only contain
valid objects of class "'>InclusionZone" (i.e., one
of its subclasses).
