Better to break compatibility upfront as part of an explicit design
decision, than to see it slowly wither away.

There has been reltively little feedback on these backwards incompatible

will be seriously backwards incompatible? Can I commit changes? Are we
agreed on the strategy "produce the best API", rather than "produce a
compatible API".

First analysis of the collection subpackage of [collections] for the
generics branch.
- BoundedCollection should be deleted/renamed to Bounded
new Bounded interface would not implement Collection, allowing it to
be implemented by Maps as well as Collections
- UnmodifiableBoundedCollection should be deleted
Just use the isFull/maxSize methods on CollectionUtils or similar
- AbstractSerializedCollectionDecorator should be deleted
Serialization can now be rolled up into the base decorator
This simplifies a lot of code
It wasn't done originally due to back-compat
- TransformedCollection will need some thinking about to generify, as
a transformer can change object types
- Consider adding a Decorator interface
This would provide a single method decorated() that obtains the
collection that has been decorated.
Whilst useful, this is also potentially dangerous exposure of state.
- Consider adding a Container interface
This would be a base super interface for Collection and Map (but
obviously we can't hack the JDK.
- Consider whether UnmodifiableCollection should be deleted as it
duplicates the JDK.
