• [Refactor adding of Implicit context providers to output #46] ImplicitContextProviders generally can be added to string representation builder output by using enum mapping values.
• [Increase test coverage up to 90 % #22] Test coverage was increased by adding additional tests.
• Renamed ProfileSettings annotation to ProfileConfig, because class name was used twice in project.
