Mathew found an undocumented feature of the LibraryImport command.
You can import datawindows into a PBD. The documentation implies that
you can only import into a PBL file.
However if you want to create and re-use dynamic datawindow in your
application they have to be in your library search path. This is great
when you're dynamically creating datawindows from a
database (using .Create) which have Dropdown Datawindows on them. You need to import the
Dropdown Datawindows dataobject definitions into the library otherwise you can't see them
on the main datawindow.
