[Insight-developers] SegmentationLevelSet template parameters

[Joshua Cates]

Hi Jim,

I believe I was using this optional template parameter to get around
problems with compilation, but I can't remember which platform was
affected (windows VC++ 6.0, maybe?).  If you are able to
correctly instantiate the parent class without it now, then please do
check in the changes.

thanks,

Josh.
