v2.2.2

Fixed

• generate() documents global scope as the CLI does. A class, struct or union outside every namespace and group has a page of its own, and the functions, variables and macros no group claims share a Globals page, whose kind is globals and whose search entries name globals as their owner's kind. A project without namespaces or groups, such as a C library, generated no pages at all, and with groups, what no group claimed was left out.
• A namespace with no description, members or types of its own, one that only wraps others such as acme around acme::net, has no page, where it read as an empty one, and the index no longer lists it. A namespace page lists the namespaces nested in it.
• A namespace's and the index's types tables list unions with the classes and structs. A union had a page of its own that no table linked to.
