- Removed jit folder (where necessary, jit functions are included in the files directly) - Implemented PointSet/GroupSet as intermediary layer between ItemSet and NodeSet/ElementSet - Removed Node and Element classes (it's much more efficient to store coords and/or inodes directly) - Swapped array indexing to be more efficient (sgrads[ip] is more efficient than sgrads[:, :, ip]) - Relaxed versioning of requirements in ENVIRONMENT.yml and setup.py - Added various helper functions to assist C++-based jive in probfem repo - Made modules explicit input argument
