Adds a `Diagnostics` component that shows the following diagnostics from the last realization: - Confirmation of success or a short description of what failed. - The value of the loss function at each step. - The spectrum of the Hessian at each step. The loss and spectrum plots are shown on switchable panels. Also includes some refactoring/renaming of existing code.
