Sampler Fit Mixture Model can now use Unique Kappa all items model

- Add: fit_mixture_model now adds a switch to use the All Items Unique Kappa mixture model fitting module.
- Add: Launchers for memory curves now use the new all items unique kappa model. Reports only the sum of nontargets. Also stores all responses, if we want to refit a mixture model later on.
Generator for Memory curves Mixed varying M

- Add: Reloading memory curve mixed, try to fit both kappa and mixture proportions for Bays 09.
- Add: While reloading memory curve mixed, we found that the EM fits were not fantastics, when fitting both kappa and mixture proportions. So create new runs to see if changing M could have an effect… Should run those with multiple ratio_conj as well.
Generator/Reloader for Fisher Info comparison with different M

- Add: Was getting bad fits for Fisher info with fixed M=400, so change it on the fly and rerun them. Works better now, for M=100.
Scatter3D on Torus fct, other tweaks

- Add: Scatter3D on a Torus. Supports both mayavi and mplot3d. Single and cool.
Launcher fisher info fits mixture model now

- Add: Launcher fisher info fit and stores the mixture model parameters
Generator fisher info single item with mixture model fits

- Add: Fits mixture model parameters directly.
