DATACMNS-1097 - Polishing.

Updated Sonargraph architecture description. Polished imports in domain package to avoid unnecessary imports (mostly due to Javadoc references).

Removed manually declared constructor in ExampleMatcherAccessor in favor of Lombok's @RequiredArgsConstructor. Removed deprecations in type information subsystem. Moved to different way of class loading to avoid null pointer warnings in ReflectionUtils.
