JPA @Identity Stragey values

Just to remember the strategies available in JPA for id generation. In most cases, AUTO will work fine as in

@Id
@GeneratedValue(strategy=GenerationType.AUTO)

Sometimes AUTO does not work. Use IDENTITY for a database that supports autoincement columns and SEQUENCE for a database that supports sequences. Few databases require TABLE

// typelog: a simple function to log the type and value of a variable
//
//     This is a short function to show the type and value of a variable that i use in my JavaScript trainings.
//     It helps students to understand what they are working with in JavaScript, since JavaScript does not
//     require programmers to provide the data type for a variable.
//
// Example:
//
//    typelog( "A string" );
//    typelog( 42 );
