Main changes

    Main APIs are now in plug-in 'org.eclipse.emf.diffmerge.generic'. Java packages follow this change in the sense that all APIs are now in package 'org.eclipse.emf.diffmerge.generic.api'. For example: IComparison, IMatch, IDifference, IMatchPolicy, IDiffPolicy, etc. Imports must thus be updated accordingly.
    Most interfaces have a type parameter that represents the type of data elements, e.g., EObject. For example: IComparison<E>, IMatchPolicy<E>.
    The application of these 'generic' APIs to EMF is still in plug-in org.eclipse.emf.diffmerge.
    The hierarchy of scopes is modified: although IModelScope and sub-interfaces / implementing classes still exist in org.eclipse.emf.diffmerge, they extend 'generic' interfaces from org.eclipse.emf.diffmerge.generic. Those extend IDataScope, and ITreeDataScope is the most useful. In many cases, it is more convenient to use ITreeDataScope<EObject> than IModelScope.
    The rules that govern data integrity and consistent manipulations are defined through IDataPolicy.

Notable fine-grained changes

    IModelScope::getContents() -> ITreeDataScope<E>::getRoots()
    IModelScope::getAllContents() -> ITreeDataScope<E>::iterator()
    IModelScope::getAllContentsAsSet() -> IModelScope::getAllContentsAsSet()
    IReferenceValuePresence::getFeature() : Object instead of EReference
    IAttributeValuePresence::getFeature() : Object instead of EAttribute
    IDiffPolicy::coverOutOfScopeValue(...) takes an additional ITreeDataScope arg
    IPersistentModelScope::getRawContents() -> IPersistentDataScope::getRawRoots()
    IPersistentModelScope::get/setExtrinsicID(...) -> IDataScope::tGetID(...)/tSetID(...)
