More progress with Swish3.

  • There is now a swish_xapian.cpp C++ example for using libswish3 with a Xapian backend. All that is complete is the indexing portion; still TODO is the search part. Still, a significant thing that it was so easy to build a search engine.
  • The swish.xml header format is complete and can now read/write the header file. Need to add that part to the swish_xapian.cpp example.
  • Squashed some long-standing memory leaks when using the filehandle functions.

Little by little.
