Hi Luis,

I noticed that you have made some changes to the FastMarchingLevelSet 
application in ITK.
I am happy to announce that these changes bypasses the problem we have 
had earlier with this application on OS X.  I have reduced the problem 
to be the use of ExpNegativeFilterType.  Changing from 
ExpNegativeFilterType to SigmoidFilterType cures the problem (some 
numerical overflow) we earlier had on OS X.

Regards
Jon
