8.3.4. Evaluation functions composition
Composition offer the possibility to build an overall new kind of TEval from the succession of
many others. It defines an ordered sequence of evaluation functions. One important thing to notice is
that composition does not deal with distribution even if it is possible. It just applies sequentially
all assessors and become really helpfull as the output of an assessor at the i-Th rank can be used as
input for the next assessor, the (i+1)-Th one. This is one by creating a TComposeEval object as
discussed briefly below.
