  ### Added
  -- Improved integration of Mint and Sidre. Mint can now operate on meshes
  +- Added jacobi_eigensolve() method for computing the eigenvalues and eigenvectors
  + of real, symmetric matrices.
  +- Added matrix_norm() operator for computing matrix norms. The implementations
  + supports the p1-norm, infinity-norm and frobenious matrix norm.
  +- Added eigen_sort() routine for sorting the supplied eigenvalues and corresponding
  + eigenvectors in ascending order.
  +- Initial integration of Mint and Sidre. Mint can now operate on meshes
  stored in Sidre and conform to the [computational mesh blueprint conventions](http://llnl-conduit.readthedocs.io/en/latest/blueprint.html).
  - Added a sphere-sphere intersection test to Primal.
  - Added a utility function to Quest to *weld* vertices in a triangle mesh that
