* An injection exception occurred when launching the MOEA DSE a second
  time from the same AF3 instance. Here, operator modules that maintain
  an internal map keep the entries of the previous run (which are
  replaced). This triggered an equals check of operator keys when the
  operators for the next execution should be placed in the internal
  operator selector maps. Within the equals check, one operator (from
  the prev. execution) had an instance of the operator such that the
  comparision would be based on the operator instances. Thus, an
  operator would be instantiated by the given injector during the
  binding phase causing the Exception.
* In order to obtain a correct operator representation in the internal
  maps an to resolve the above problem, base the Operator Key hash and
  equals method on the OperatorTypes only. We only allow one operator
  type per genotype anyways such that the new equals operation correctly
  implements the concept and "old" operator instances are cleaned out.

* Use scope enter and exit calls to clean cached objects in thread-

* ExplorationFeatures:
** Add a method to the IExplorationFeatures that checks whether the
   available input system models justify the application of a certain
   feature. This is intended to detect cases where an ExplorationFeature
   would degenerate to a No-Op such that it is useless to be executed.
** Add a utility method that returns the set of ExplorationFeatures,
   which are enabled by the user (by a DseSpecificiation) and applicable
   to the given input system models.
** Change the ExplorationFeature(Service) such that a stronger coupling
   between Genotypes and its Creators and Operators exist: It is
   required to correctly register the operators with their corresponding
   Genotypes.
* Copying:
** Add a "Copyable" interface that enforces the existence of a copy
   statement. This is the inverse approach as the Cloneable marker
   interface of Java.
** Add a mechanism that installs a default CopyModule if no specialized
   CopyModule is provided for a given Genotype. This implementation
   relies on the existence of the Copyable interface for each Genotype.

* Switch the ExplorationEvaluationService to not rely on eclipse
  extension points but use java registration methods. This service has
  now a close relation to the ExplorationFeatureService that holds all
  ExplorationModules.
  Additional information and logic required for evaluation is found in
  the ExplorationEvaluationService.
* Register the MappingEvaluatorObjective for DSML Expressions and the
  EvaluatorModules specific for the ParitionExploration.
* Add the @Provides annotation to each evaluation function such that
  their method parameters are automatically injected by Guice.
* Extract the parsing of IExpressions to parsers which are called from
  the corresponding IExplorationModules.
* Provisioning interception:
  * Generalize the DecodingInterceptor into a ProvisionInterceptor such
    that it can be used for the create phase as well. Along, make the
    update mechanism via sub-modules providing same types optional (used
    only in the decode phase).
  * Add an Interceptor module such that already created Genotypes can be
    provided to other create methods that depend upon them. This avoids
    launching the create method for the same time several times, causing
    inconsistencies between the Genotypes.
  * Add a @Creates annotation for method interception binding.
* Add additionally required @Provides annotation in the
  SystemModelAdaper.
* Create a TaskMapper that encapsulates the Task -> ITaskAdapter
  associations. It is used, for instance, in the evaluators where the
  ExplorationTargets are defined on AF3 elements whereas the DSE
  internally works on reduced elements.
* Remove the non-used cglib library.
* Add the ByteBuddy library (v1.8.17) to be able to generate code at
  runtime. It is used to generate Provider Classes (using @Provides
  methods) that are supplied to the injectors of follow up phases (e.g.,
  decode -> evaluate) such that previous results are available to these
  injectors.
* NOTE / IMPORTANT: This commit leaves several outdated and (now) unused
  classes in place. They will be removed in follow up commits.

* If a phenotype is requested as an input parameter by multiple

* Extend the decoding interceptor such that it request the map of
  already decoded phenotypes and looks for already decoded phenotypes.
  If one is found it is returned instaed of invoking the decode method.
* All decode methods are now intercepted by the above mentioned
  interceptor. Decode methods MUST be annotated with "@Decodes" from now
  on.
* Plugin-style decoders are still supported by marking Phenotypes if
  they are processed by sub-decoders. Otherwise, only sub-decoders would

* Update Guice to a self-compile version that allows overriding
  @Provides methods.
* Create an "@PluginDecoder" annotation along with a MethodInterceptor
  that intercepts such annotated decode methods. It launches all decode
  methods that provide the same phenotype prior to executing itself
  (sub-decoding). These sub-decoders are providing updates to the
  phenotype before the actual decoding is executed.
  NOTE: Sub-decoder methods must be annotated with the "@Named("XYZ")"
  key where XYZ is the class name of the decoder. This is required to
  avoid @Provides methods that would return the same type.
* Re-create the DecoderModules by the Guice Injector before passing them

  before the GuiceDecoder is instantiated.

* 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.

* Add a mechanism to analyze the Guice dependency graph to
  collect the set of genotypes that is required to obtain a
  requested Phenotype. The code is a modified version of
  the dependency graphs calculated within Guice's Grapher
  extension). The list of required Genotypes determines
  the list of creators to be launched.

* Create a top-most injector (DSE injector) when the explorer is
  created. It hosts the Opt4J injector and allows accessing data from
  the DSE from within Opt4J Modules.
* Enable Multi-Operator bindings (multiple operators from which one is
  selected to be applied on the same Genotype-Type) by the Operator's
  type. This is required to allow injecting DSE-wide parameters, e.g.,
  system model data.
  * Use a OperatorKey to allow registering Operators Objects or their
    Classes in the selection map.
  * Operators registered by their type are initialized lazily when they
    are delivered by the OperatorSelector on request.
* Remove various dependencies on the SystemModelAdapter (Use DI where
  data is needed). This allows to break up very complex inheritance
  hierarchies.
* Extend the SystemModelAdapter to use @Provides annotations that are
  used in opt4j modules (e.g. decoders) to obtain system model data.

  for the SystemModelAdapter since they will be removed soon due to the

* Service for adding Exploration Modules to the DSE. The define the
  concrete problems that shall be solved by the DSE process. Modules
  registered with this service are known to the DSE and can be selected
  by users to define a DSE process. The Modules registered here are not
  defining a concrete DSE process, just the concrete problems.
* Exploration modules can be categorized into three classes: Variable
  definitions, Problem statements and transformations, and Evaluators
  (solution metrics). The variable definitions consist of a Genotypes
  (variables), Operators (modify variables), and Creators (variable
  initialization). Problem statements transform Genotypes into
  evaluable solutions implemented by Decoders that produce Phenotypes.
  Evaluators rate Phenotypes such that the quality of a solution can be
  quantified.
* The complete DSE process is based on DI:Creators, Operators, Decoders,
  and Evaluators have to be implemented as Guice AbstractModules.
  Therefore, the package org.fortiss.af3.exploration.alg.dse.module
