Main result: (appropriate versions of) bilinearity, 'graded' commutativity and the Jacobi identity for generalised Whitehead products. These are all found in Cubical.Homotopy.WhiteheadProducts.Generalised.Properties
Some refactoring: gave Whitehead products their own file under Cubical.Homotopy.
Co-H-Space structure on joins.
WIP:
Lift everything to WH products on homotopy groups -- all results are in the library, just a matter of combining them...
