lucas - added pretty printing function and cleaned up signature a little.

lucas - fixed bug in changing focus - when moving up and right, if an abs was encountered it would move up an extra time. I also removed the spurious pretty printing function that did nothing.

New command: interpretation in locales.

added finite(option) to Recdef.thy

added selectors 'classes_of' and 'classes_arities_of'

exported dest_def

added 'the_const_constraint'

(added to repository)
