Start and end have been renamed to head and tail.

Hi

I have on old eigen2 function working with dense matrices

template<typename Derived>

void process(MatrixBase<Derived>& DATA) {
 Vector2d G;
 G << 1.0, 2.0;

 DATA.template start<2>()+= G;    // fails in Eigen3
 DATA.template segment<2>(0)+= G;

}

How can this be upgraded to Eigen3.
Many thanks for a hint,
Helmut.
