## [0.9.0]
## Modified
* Renamed:
- `::from_col_vector` -> `::from_column_vector`
- `::from_col_iter` -> `::from_column_iter`
- `.col_slice` -> `.column_slice`
- `.set_col` -> `.set_column`
- `::canonical_basis_with_dim` -> `::canonical_basis_with_dimension`
## [0.8.0]
## Modified
* Almost everything (types, methods, and traits) now use full names instead
