#292 Compile error with GCC 4.7

[Eric Smith]

It looks like GCC is getting more strict about C++ rules again. With GCC 4.7 and Meshlab 1.3.1, I now get the errors listed below. The fix is probably quite simple, but I don't understand C++ templates and namespaces well enough to figure it out.

Thanks,
we have repaired it, hope its working for You now.

It's broken again in v1.3.2 as of March 2013.
