7 * This example demonstrates the usage of Eina Model by implementing
8 * Bank Account Class, which is inherited from Base Class;
9 * and Credit Card Class, which is inherited from Bank Account Class.
10 *
11 * Base Class(Eina_Model_Type) --> Bank Account Class --> Credit Card Class
12 *
13 * Bank Account Class implements "bank_account_data_set()" and "print()" methods;
14 * Credit Card Class inherits these two and implements "credit_card_data_set()"
15 *
16 *
17 * Bank Account Class::print() calls for "_bank_account_data_print"
18 * Credit Card Class ::print() is reloaded with "_credit_card_data_print()"
19 * which calls for parent function "_bank_account_data_print"
