* Derive some of the EA parameters from the population size.
* Clean-up the implementation of the implicit ExplorationTarget
  addition to the ExplorationSpecification passed to the solver. It is
  now encapsulated in the "Explorer".

* The previous parameter set caused the optimizer to spend half of the
  iterations for random generation, not the search itself. Now, only the
  first 5 iterations are spent on the creation of the initial pool.
* Adjust the default of the parallel execution to "true".

* The IExplorationFeatureService allows to add extensions to the DSE
  process that consist of sub-modules, e.g., Variables, Evaluations,
  or additional operations on existing encodings.
* While the IExplorationFeatureService is used to manage all existing
  extensions, the activated ones (configuration) is passed to the DSE
  by the exploration backend. Currently, the activated features are hard
  coded, but shall be moved to the UI.
* Consequently, the IExplorationModuleService has bee removed. Its
  functionality has been moved to the ExplorationFeature abstract class
  that are single features registered with the
  IExplorationFeatureService.
* The activated features now govern the installation of the sub-modules
  (Creators, Decoders), instead of the previous
  IExplorationModuleService.
* When setting up the Opt4J exploration, the activated decoder
  configuration is now checked for consistency to avoid circular
  dependencies and duplicate responsibilities of decoders to create a
  phenotype.
* An IExplorationFeature type is added to the MOEA ecore model to allow
  referencing exploration features from EMF classes.

* Create a GuiceDecoder class that serves as a container at which
  Guice-based decoders can be registered. It calls the Decoder that
  provides the demanded output encoding (Provides annotation). The
  Guice injector will be responsible to resolve the dependencies between
  the decoders.
* Simplify the Phenotype classes such that there exists only a single
  phenotype that can host sub-phenotypes.
* Also remove the generic from the phenotype that declares it's primary
  input genotype: There is almost no gain in terms of safety/robustness
  versus a ton of code complications.
