[Nitro] [PATCH] Entity copying methods

Hi Robb,
  I was one of the requesters so thanks for your work! Some comments follow.

Wouldn't it be possible to recursively copy/clone the weak entity
(optionally)? That would make this patch perfect for my needs.

Do joins made through another Class also copy the join data? For example

class A
 joins_many B, :through =>C
end

class B
 joins_many A, :through =>C
end

class C
end

Will this also copy the join data contained in C?

A lot of thanks for your work Rob!

Cheers,
