Description:

these are much like InterestConverters; however, the reference to
the destination is weak, which allows for them to be garbage collected.

Class protocol:

 destination: anObject selector: aSelector

create & return an interestConverter, which sends aSelector
to anObject when a change notification arrives

 destination: anObject selector: aSelector aspect: aspect

create & return an interestConverter, which sends aSelector
to anObject when a change notification for aspect arrives

Instance protocol:

 aspect

return my aspect (if any)

 destination

return my destination

 destination: dest selector: sel

set destination and selector

 destination: dest selector: sel aspect: a

set destination, selector and aspect

 update: something with: aParameter from: someObject
