A thought about this: maybe I can pass in the name of what I'd like the 
entry field to be called as another parameter, then after the entry 
object is created I can say something like:

self.<myname> = self.entry

Of course, I'm not sure how to write the left side, because I assume I'd 
have to pass in my new name as a string, but a string wouldn't work as 
an instance variable.

Also, would there be any problems with this kind of assignment? Any 
weird reference problems that makes this not really work?
