Excessive use of memory caused by storing all Pareto-optimal solutions for multi-objective symbolic regression runs

Description
The MultiObjectiveAnalyzer produces an ItemList which collects all Pareto-optimal solutions. Solution objects are rather heavy which leads to excessive memory usage especially for problems with many objectives.
Proposed fix: do not create and collect solution objects. The analyzers already collect all the required information to generate the solution objects after the run on demand. A specific SolutionView could be used to allow easy lazy access to solution objects via the GUI.

This can be solved easily by deactivating the analyzer.
