Exposes all top-level callables within a module. The module's __all__
attribute is respected, if it exists. Names beginning with underscore
are ignored.
Uses the first component of PATH_INFO as the callable's name and if
empty, will instead use self.index_page.
Upon successful resolution, appends the callable's name to SCRIPT_NAME
and updates PATH_INFO as the remaining components of the path.
NB: I would recommend explicitly setting the module's __all__ list.
Otherwise, be sure all the names of module-level callables that you
don't want exported begin with underscore.
