+#### Решение упражнения №4
+По заданию нужно ограничить контекст заданными бинами, с помощью внешней конфигурации. 
+
+Вешаем @SpringBootConfiguration над внешним классом TestSpringBootConfiguration. 
+Теперь сканирование конфигураций не уйдет далше него. Ни одного бина не найдется.
+Значит нужно формировать контекст самим. 
+
+По заданию в нем должны быть бины типов Mother, Son и Father. Первые два являются @Component.
+Их можно разместить в контексте просканировав соответствующие пакеты с помощью @ComponentScan
+  
+Т.к. Father НЕ является @Component, то для его размещения в контексте нужно его создать, 
+через метод с аннотацией @Bean внутри тестовой конфигурации
