        DeferredImport

A trivial deferred module loader.

Use this to delay the actual import of a module until it's actually
needed.

It is constructed with a module name (that will be inserted into the
calling module's globals() as a side effect) and some literal code
that, when executed in the caller's global namespace, actually
imports the module, for instance::

        utils.DeferredImport("wcs", "from astropy import wcs")

As a service for static code checking, you'll usually want to repeat
the module name, though:


        wcs = utils.DeferredImport("wcs", "from astropy import wcs")
