feat: new mp_lib2inserts macro. In addition, modified mp_getddl to ignore views, closing #5. Created a test, which highlighted another issue in mp_getddl (labels were being double quoted which caused macro resolution attempts when %including). Changed to single quotes. Switched 'outlib' to 'outschema' in mp_ds2inserts to harmonise with mp_getddl. Added a maxobs option, to speed up testing.
