SparseGridTest.cpp is missing header algorithm

[expeditioneer]

The SparseGridTest.cpp is missing the include of the algorithm header from the STL. When compiling on gentoo with recent gtest (1.10) it produces the following error:

After adding +#include <algorithm> to SparseGridTest.cpp everything works fine.
