- Oersted field computation helper class in [cmtj/models/oersted.py](cmtj/models/oersted.py). Basic functionality is there, but needs to be futher tested and documented. Next release potentially will move the computation to C++ for speed.
- Added Heun (2nd order) solver and made it default for thermal computation. This is a more stable solver than the Euler solver, but is slower. The Euler solver is still available as an option.
- Stack class now supports arbitrary layer ids to be coupled.
- Extended the plotting capabilities of the Stack class. Now supports plotting of the magnetic field and the current density.
- Added alternative STT formulation which in some cases may be useful.
- Fixed some minor bugs in the thermal solver.
- Fixed some minor bugs in the Stack class.
- Updating tutorials on the docs page.
- Bunch of extra documentation and examples.
