applications: prove almost completely that S^3 and S^2 have the same high enough homotopy groups
...
There is one missing fact, which is that the equivalence between S^1 and the fiber of the hopf fibration respects the basepoint

Finish construction of the LES of homotopy groups without signs
...
The maps on every level are just the functorial action of the homotopy groups (possibly composed by a cast), but there are no compositions with path inversion.
There are also some updates in various files after changes in the HoTT library.

Add computing version of the LES of homotopy groups.
...
Start on applications of the LES.
Also finish proofs in sec83 (I've also included them in the latest pull request for the Lean-HoTT library).
