ok, the changes are done.

here's an example of how to use full precision as the default:

#define EIGEN_DEFAULT_IO_FORMAT IOFormat(FullPrecision)
#include<Eigen/Eigen>
int main() {
  std::cout << Eigen::Matrix4d::Random() << std::endl;
}

columns are aligned by default, pass DontAlignCols to IOFormat ctor to disable.
