I didn't see a method like this in Math Utils yet. It's pretty basic and helpful, so I think it would be beneficial.

fixed in subversion repository as of r770798
The methods have been put in MathUtils instead of a dedicated GeometryUtil.
An error in the double version has been fixed (int sum instead of double sum).
In addition to the L2 (euclidean) distance, the L1 and Linf distances have also been added.
thanks for the report and for the patch

Thanks Luc.
(FYI, ~~MATH-266~~ made use of GeometryUtil, and will need just a minor tweak to MathUtils in order to compile.)
