ImGui App Module (Application abstration)

New module provides an abstraction layer to create ImGui applications. It hides all low-level routine. Every life-cycle method could be overriden with custom logic, so you can extend class in the way you need. Or just keep it as it is, if need nothing specific. Simple application may look like this:

import imgui.ImGui;
import imgui.app.Application;

public class Main extends Application {
    @Override
    protected void configure(Configuration config) {
        config.setTitle("Dear ImGui is Awesome!");
    }

    @Override
    public void process() {
        ImGui.text("Hello, World!");
    }

    public static void main(String[] args) {
        launch(new Main());
    }
}
