/**
 * Rule comparing the value of the field with some other value
 *
 * The Rule needs two configuration parameters for its work
 *  - comparison operator (defaults to equality)
 *  - operand to compare with; this can be either a constant or another form
 *    element (its value will be used)
 * See {@link mergeConfig()} for description of possible ways to pass
 * configuration parameters.
 *
 * Note that 'less than [or equal]' and 'greater than [or equal]' operators
 * compare the operands numerically, since this is considered as more useful
 * approach by the authors.
 *
 * For convenience, this Rule is already registered in the Factory with the
 * names 'eq', 'neq', 'lt', 'gt', 'lte', 'gte' corresponding to the relevant
 * operators:
 * <code>
 * $password->addRule('eq', 'Passwords do not match', $passwordRepeat);
 * $orderQty->addRule('lte', 'Should not order more than 10 of these', 10);
 * </code>
