Hi Brad,

The code was compiled with g++, gcc version 4.5.2 (Ubuntu/Linaro 
4.5.2-8ubuntu4). For the Gerardus ItkToolbox I use flag -O2, although to 
be honest I'm not sure whether the compilation of ITK as Release uses it.

Of course, if I see anything I can improve I'll send a patch ;)

Cheers,

Ramon.
