 * Simple relationship handler that allows a new version of the primary table

 *
 * The base relationship handler can only handle a single join. Some
 * relationships are more complex and might require chains of joins; for those,
 * you must use a custom relationship handler.
 *
 * Definition items:
 * - base: The new base table this relationship will be adding. This does not
 *   have to be a declared base table, but if there are no tables that
 *   use this base table, it won't be very effective.
 * - base field: The field to use in the relationship; if left out this will be
 *   assumed to be the primary field.
 * - relationship table: The actual table this relationship operates against.
 *   This is analogous to using a 'table' override.
 * - relationship field: The actual field this relationship operates against.
 *   This is analogous to using a 'real field' override.
 * - label: The default label to provide for this relationship, which is
 *   shown in parentheses next to any field/sort/filter/argument that uses
 *   the relationship.
