- Kurtosis now is computed as a function of the projection of the trajectory along the principal axis.
- Diffusivity was removed from the set of features computed in the function compute_features() because the expression implemented is only meant to be used for normal diffusion. In the next versions we expect to implement Green-Kubo relation to compute diffusivity for every kind of trajectory. Since trappedness is calculated based on the diffusivity, we also removed from the standard set of features.
