The files `Mathlib.LinearAlgebra.FreeModule.Rank`, `Mathlib.LinearAlgebra.FreeModule.Finite.Rank`, `Mathlib.LinearAlgebra.Dimension` and `Mathlib.LinearAlgebra.Finrank` were reorganized into a
folder `Mathlib.LinearAlgebra.Dimension`, containing the following files
- `Basic.lean`: Contains the definition of `Module.rank`.
- `Finrank.lean`: Contains the definition of `FiniteDimensional.finrank`.
- `StrongRankCondition.lean`: Contains results about `rank` and `finrank`
over rings satisfying strong rank condition
- `Free.lean`: Contains results about `rank` and `finrank` of free modules
- `Finite.lean`: Contains conditions or consequences for `rank` to be finite or zero
- `Constructions.lean`: Contains the calculation of the `rank` of various constructions.
- `DivisionRing.lean`: Contains results about `rank` and `finrank` of spaces over division rings.
- `LinearMap.lean`: Contains results about `LinearMap.rank`
API changes:
`IsNoetherian.rank_lt_aleph0` and `FiniteDimensional.rank_lt_aleph0` are replaced with
`rank_lt_aleph0`.
`Module.Free.finite_basis` was renamed to `Module.Finite.finite_basis`.
`FiniteDimensional.finrank_eq_rank` was renamed to `finrank_eq_rank`.
`rank_eq_cardinal_basis` and `rank_eq_cardinal_basis'` were removed
in favour of `Basis.mk_eq_mk` and `Basis.mk_eq_mk''`.
