Program Structure
Now, examine how your program was written in haXe. When writing an application using the haXe
language, you will extend upon the class hierarchies that already exist in the haXe framework. These
classes will eventually form one of two purposes: a runnable program or a code library. Both hierarchical

structures are identical in approach, except that a runnable program will expose a static function called
main that will be run when the program is first executed, just as you have in the HelloWorld example:
public static function main()
{
....
}
This is known as the entry point and is responsible for initializing your application and calling the logic
that will facilitate the rest of your program.
