[Zope] testing for folders

[Casey Duncan]

isAUserFolder: self explanatory

isAnObjectManager: Subclasses object manager, the standard Zope object 
container.

isPrincipiaFolderish: Is a container object, possibly other than an 
object manager.

In short, all object managers are folderish, but not all folderish 
objects are object managers.

You shouldn't need to worry about this though since all user folders are 
always named "acl_users" AFAIK. Just look for objects with that id 
recursively. ZopeFind may be of help for this.
