The `EnsembleProblem` returned by a `build_ensemble` function contains internal variables which are not reset after `solve` is called. A convenient `reset!` function may be provided to for those objects to...
Better implementation of `project_to_lowlevel` to take care of the degenerate energy levels. Possible enhancements includes: - [ ] Taking higher order derivatives as input and implement the method described here:...
Right now, only `DenseHamiltonian` and `SparseHamiltonian` supports user defined `EIGS` and `eigen_decomp`. The can be extended to other `AbstractHamiltonian` types.

The interfaces changed for v0.7.0. Need a new tutorial.
