* @note: by default, the firsts of the five operators are selected.
*
* If you don't (want to) recall the order of the operators in the encoding,
* you can use the `index_of` member, for example:
* you can use the `index()` member, for example:
* @code
* foundry.at(foundry.index_of.continuators) = 2; // select the third continuator
* foundry.at(foundry.continuators.index()) = 2; // select the third continuator
* @endcode
*
* Now, you can call the fourdry just like any eoAlgo, by passing it an eoPop:
* @code
* foundry(pop);
* @encode
* It will instanciate the needed operators (only) and the algorithm itself on-the-fly,
* It will instantiate the needed operators (only) and the algorithm itself on-the-fly,
* and then run it.
*
* @note: Thanks to the underlying eoForgeVector, not all the added operators are instanciated.
* Every instanciation is deferred upon actual use. That way, you can still reconfigure them
* @note: Thanks to the underlying eoOperatorFoundry, not all the added operators are instantiated.

* @code
* foundry.selector.at(0).setup(0.5); // using constructor's arguments
