/**

* skdiff
|
|
*
|
|
* Given three directory names, expects to find identically-named files in
|
|
* each of the first two; the first are treated as a set of baseline,
|
|
* the second a set of variant images, and a diff image is written into the
|
|
* third directory for each pair.
|
|
* Creates an index.html in the current third directory to compare each
|
|
* pair that does not match exactly.
|
|
* Recursively descends directories, unless run with --norecurse.
|
|
*
|
|
* Returns zero exit code if all images match across baseDir and comparisonDir.
