 * 
 * Place on a parent model of the One-to-many relationship if the tables do not follow
 * the ActiveJDBC naming conventions.
 * 
 * 
 *     This annotation will do exactly the same as {@link BelongsTo}, but is placed on a 'parent' side of a relationship.
 * 
 *
 * 
 *     There is no need to add both {@link HasMany} and {@link BelongsTo} on the two related models. Just one is
 *     fully sufficient.
