Code for computation of Coulomb integrals of Hermite Gaussians, using the the McMurchie-Davidson scheme as described in the book "Molecular electronic-structure theory" by Trygve Helgaker, Poul Jorgensen, and Jeppe Olsen
Tests some basic math functions such as template_blas_sqrt()template_blas_log() etc to see that they are working properly and that they deliver the expected accuracy
Tests the explicit computation of 2-electron integrals by moving basis functions by small distances and verifying that the computed 2-el integrals vary smoothly
