* fix multiple temporary copies for coeff based products

* introduce a lazy product version of the coefficient based implementation
=> flagged is not used anymore
=> small outer product are now lazy by default (aliasing is really unlikely for outer products)

* add a few cwiseXxx functions

(vec1*vec2.transpose())*vec3
Gael, no objection? Seems to make sense as that's fast.

big refactoring in Product.h:
...
- all specialized products now inherits ProductBase
- the default product evaluated by Assign is still here,
but it is currently enabled for small fixed sizes only
- => this significantly speed up compilation for large matrices
- I left the OuterProduct specialization empty as an exercise...
