* refactoring of Product:

Browse Source 
* use ProductReturnType<>::Type to get the correct Product xpr type
  * Product is no longer instanciated for xpr types which are evaluated
  * vectorization of "a.transpose() * b" for the normal product (small and fixed-size matrix)
  * some cleanning
* removed ArrayBase
