Detailed Description

This is the context on which we read a fitness expression, and parse it to identify all variables in the expression.

The variables are collected in a list

            }
        }

This mapper does not map variables, but it creates an instance of Variable named with the given string, and it adds the instance to the list of known variables, if no variable with the same name is already there.

Variable names are expected to correspond to the name of descriptors
