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.)

assume aliasing for that expression (that is, for products)

AllAtOnce traversal
* Implement EvalToTemp expression object

Make product eval-at-once.
...
* Make product EvalAtOnce in cases OuterProduct, GemmProduct and
GemvProduct
* Ensure that product evaluators are nested inside EvalToTemp
evaluator
* As temporary kludge, evaluate expression to temporary in AllAtOnce
traversal and pass expression operator to evalTo()

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.

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