 * Stands for an atomic settings element. The general idea is to allow third-party plugin developers to use platform
 * codebase for managing arrangement settings, that's why we need a general purpose class that represent a setting.
 * I.e. third-party developers can create their own instances of this class and implement {@link ArrangementStandardSettingsAware}.
