Lazy module class.
Lazy modules are imported into the given namespaces whenever a
non-special attribute (there are some attributes like __doc__ that class
instances handle without calling __getattr__) is requested. The module is
then registered under the given name in locals usually replacing the
import wrapper instance. The import itself is done using globals as
global namespace.
Example of creating a lazy load module:
ISO = LazyModule('ISO',locals(),globals())
Later, requesting an attribute from ISO will load the module
automatically into the locals() namespace, overriding the LazyModule
instance:
t = ISO.Week(1998,1,1)

(Constructor)

Create a LazyModule instance wrapping module name.
The module will later on be registered in locals under the given
module name.
globals is optional and defaults to locals.
