JPA Assignment 1
                
        I gave you the City Entity class that maps to the City DB Table
        
        this afternoon I want you to write the Country Entity class
        that will map to the Country DB Table
        
        CREATE TABLE COUNTRY (
                CODE CHAR(3) NOT NULL,
                NAME CHAR(52) NOT NULL,
                CONTINENT VARCHAR(15),
                REGION CHAR(26) NOT NULL,
                SURFACE_AREA DECIMAL(10,2) NOT NULL,
                INDEP_YEAR SMALLINT,
                POPULATION INTEGER NOT NULL,
                LIFE_EXPECTANCY DECIMAL(3,1),
                GNP DECIMAL(10,2),
                LOCALNAME CHAR(45),
                GOVERNMENT_FORM CHAR(45),
                CAPITAL INTEGER,
                CODE2 CHAR(2),
                CONSTRAINT PK_COUNTRY PRIMARY KEY (CODE)
        );  
        
        
        the steps are:
        
        0) create the Java class, generate get/set and a default constructor 
        1) Map the class name to the Table name w/ @Entity annotation
        2) Map the @Id
        3) Map each field in the class (or mark it transient)
        
        
        at some point you will need to code:
        the JavaDocs
        the business rules for get/set methods
        the JUnit Tests
        toString method
        hashCode and equals methods
