On finding names

We are not trying for a general solution to the problem of "find the item that is being referred to" - we are just trying to provide useful links between <interpreted> items in docstrings and those things that they might reasonably be expected to be referring to.

Some rules thus occur.

1. We will not show attributes, docstring or not, if they are not

   1. At module level (so a ModuleValue)

   2. Within a class (so a ClassValue)

   3. Within a method called __init__ or __new__.

   So discard any attributes that do not match these criteria.

Hmm - is that the only rule? Can it be so simple?
