[ZWeb] Organization of Zope API Reference

[Don Hopkins]

I've gone through the Zope API reference and made an index of all the
modules and classes, to stimulate discussion about how to improve the
API reference. This is just a first cut to figure out what's there and
how to approach indexing and categorizing it. 

Most modules in the API reference only contain one class of the same
name, but a few modules have no classes or one or more differently named
classes. So maybe it would be better to have a class name index, but
indexing modules without classes as if they were classes.

I've categorized modules and classes, based on how they're used, and how
important I think they are to the Zope programmer. Classes or modules
can be in more than one category: just one exclusive category, and any
number of modifier categories. 

Here are the proposed categories so far:

Exclusive categories (used to classify categories based on how they're
used):

    Core - A core class that many other classes inherit from.
    Content - A content class that occurs in the Zope database.
    Utility - A utility class called by other code, but not instantiated
as content in the Zope database. 

Modifier categories (used to modify classes based on how important they
are):

    Common - Commonly used, should be easy to find. (modifier category)
    Obsolete - Rarely used, should not be emphasized. (modifier
category)

I've marked all the Core categories as Common since they're important to
know, as well as the Utility classes Request and Response, but the other
utilities are not common. 
I've marked the PropertySheet and PropertySheets classes as Obsolete,
because I believe they have to do with ZClasses, which everyone in their
right mind knows well enough to avoid. 

This list doesn't look complete to me. I think there are probably a
bunch more classes that should be documented in the API reference, but
here are the ones that are currently documented. 

This list is just a straw man to stimulate discussion of how to
reorganize the API reference, so please feel free to suggest changes.
