Several improvements to the handling of boxes

Micael Oliveirarequested to merge
more_box_improvements into develop

Description

Several changes:

  • Cylinder boxes are now always along the direction defined by the first basis vector.
  • Optimize box_shape_contains_points by using BLAS to change the point's coordinates.
  • Make basis_vectors optional when initializing a box_shape.
  • Rename box_shape basis_vectors to axes to make its meaning clearer.
  • Add several missing private statements in the box modules.
