I rebuilt the wrappings with UC support.

The very basic functions work for me now.

I can run my toy program for highlighting image differences in the
"spot N differences" style games.

Sample usage:

CLASSPATH=/usr/share/java/org.itk.io.jar:/usr/share/java/org.itk.compose.jar:/usr/share/java/org.itk.calculators.jar
VERIFY_JRUBY=1 jruby cimgdiff.rb YM ../flower1l.png ../flower1r.png
flower_1ym.png

Setting VERIFY_JRUBY is a hack to run JRuby programs that load
libraries without modification to standard JRuby installation.

Thanks

Michal
