/**
 * Spring Boot {@link EnableAutoConfiguration auto-configuration} for Spring Data for Apache Geode (SDG) Repositories.
 *
 * Activates when there is a bean of type {@link Cache} or {@link ClientCache} configured in the Spring context,
 * the Spring Data Geode {@link GemfireRepository} type is on the classpath, and no other existing
 * {@link GemfireRepository GemfireRepositories} are configured.
 *
 * Once in effect, the auto-configuration is the equivalent of enabling Geode Repositories using the
 * {@link EnableGemfireRepositories} annotation.
