Version 3

3.0.0

- Remove createPureProduct in favor of pure
No need to create multiple pureProduct, only one is required
- Talent are now called with the product they will output
It looks a bit like a constructor with this set to the created object so that you got a pointer on it
- Restore valueOf on product passed to talent
We need a pointer to the talentedProduct in many case.
- Product are now frozen objects
Cannot add new properties
Cannot reconfigure existing properties
- Much more documentation
- One talent per product
This is an implementation detail but now a product does not hold a list of talent
