Introduce configurable stopping criterions

Summary

Introduce configurable stopping criterions to all implemented optimisation algorithms.

Component

• Documentation
• Eclipse
• evoal.core
• generator.main
• optimisation.ea
• optimisation.hc
• optimisation.pso
• optimisation.sa
• optimisation.ta
• surrogate.adaption
• surrogate.smile

Use Case

Stopping after a fixed amount of iterations is not always the desired way of stopping an optimisation algorithm. Therefore, it should be configurable.
