CW complex + Weakly contractible => Contractible, which is a weak version of the Whitehead theorem.

This is a major theorem and will most likely be the mathematically hardest theorem we have in pi base.

@prabau this is a really important theorem. In my opinion with this we have all the homotopy theorems we really need in pibase.
