### Changed

- All weighting, normalization, and ranking methods are implemented for the `DMatrix<f64>` type.
- Moved from `ndarray` to `nalgebra` for matrix types.

### Added

- More ranking methods.
- More weighting tests.
- Function named `switch` to `CriteriaTypes`. Useful for weighting methods like `MEREC`.

- - Tests now return appropriate errors instead of panicing on failures.

### Fixed

- Entropy and MEREC weighting method documentation to add more clarity.
- Entopy weighting calculation.
- Doc typos and clarity.
- Getting more disciplined at actually trying to better follow semantic versioning.
