/**
 * Central repository marker interface. Captures the domain type to manage as well as the domain type's id type. General
 * purpose is to hold type information as well as being able to discover interfaces that extend this one during
 * classpath scanning for easy Spring bean creation.
 * 

 * Domain repositories extending this interface can selectively expose CRUD methods by simply declaring methods of the
 * same signature as those declared in {@link CrudRepository}.
 * 
 * @see CrudRepository
 * @param  the domain type the repository manages
 * @param  the type of the id of the entity the repository manages
