This CL looks bigger than it really is. :-)

There's only one source file with changes: skdiff_main.cpp.

Most of the added and deleted files are where I moved the test images into a
hierarchical structure (to test the change).

The modified index.html and stdout files show how the skdiff output has changed.

LGTM

Added Eric to reviewers to look at 	 tools/skdiff_main.cpp for C++ readability.

Sounds good.  Eric, I'll wait for you to take a look.
