bug #99 : refactor assignment and compound assignment mechanism through "assignment functors" and "assignement kernels".
...
The former is very low level and generic. The later abstarct the former for dense expressions. This refactoring permits
to get rid of the very ugly SwapWrapper and SelfCwiseBinaryOp classes.
In the future, this will also permit to simplify all these evaluation loops and perhaps to reuse them for reduxions.
That will also permit to specialize for operations like expr1 += expr2 outside Eigen, and so for any kind
of expressions (dense, sparse, tensor, etc.)

* Make product EvalAtOnce in cases OuterProduct, GemmProduct and

Implement eval-at-once in evaluator.
...
- Add evaluator_traits with HasEvalTo flag, which is true if evaluator
has evalTo() function.
- Add AllAtOnce traversal, which calls evalTo() in evaluator.
- If source evaluator in copy_using_evaluator has HasEvalTo set, then
use AllAtOnce traversal.

* Copy implementation from GeneralProduct in InnerProduct case.
* For GeneralProduct in other cases, call the evalTo() member function with
expression objects in constructor of evaluator.
