[Mono-list] ArrayList.Adapter to be implemented

[Nick Drochak]

Hi all.

I've fixed all the bugs revealed by the unit tests for ArrayList, except
for implementing the Adapter() method.  I believe there was some
discussion on IRC about this, so I'll leave it for someone else, or
perhaps someone could post what the design decisions were.

There are a couple of classes/structs in System.Collections that do not
have Nunit tests written for them:
  DictionaryBase
  DictionaryEntry

Anyone want to volunteer to do these?
