-/** \class ei_new_allocator
-*
-* \brief stl compatible allocator to use with with fixed-size vector and matrix types
-*
-* STL allocator simply wrapping operators new[] and delete[]. Unlike GCC's default new_allocator,
-* ei_new_allocator call operator new on the type \a T and not the general new operator ignoring
-* overloaded version of operator new.

-* Example:
-* \code
-* // Vector4f requires 16 bytes alignment:
-* std::vector<Vector4f,ei_new_allocator<Vector4f> > dataVec4;
-* // Vector3f does not require 16 bytes alignment, no need to use Eigen's allocator:
-* std::vector<Vector3f> dataVec3;
