[lvm-devel] [PATCH 0/4] Cleanup lvm2app.h doxygen documentation and add example.

[Dave Wysochanski]

This patchset cleans up some of the lvm2app.h doxygen tags and
moves us closer to more useful documentation.
Included is an intial Doxygen file, as well as example code that
along being part of the documentation, gets built in the nightly
lvm2app tests.

Should apply cleanly on top of the 8 tags patches posted earlier.
