Cleanup patch

[Stefan Seefeld <stefan@xxxxxxxxxxxxxxxx>]

The attached patch does some cleanup in order to enhance
header independency:

* view_traits.hpp forward-declares views with all default
  arguments, which vector.hpp, matrix.hpp, and tensor.hpp
  then don't issue a second time.
* dense.hpp doesn't depend on view_traits.hpp
* expr_functor.hpp depends on expr_binary_operators.hpp
* matvec.hpp requires promote.hpp and fns_elementwise.hpp
  to be self-contained.

Ok to commit ?

Regards,
		Stefan
