In order for the video to be more understandable, I have split the development process into 5 main sub tasks:
Create New Project
Locate Classes
Map Classes
Instantiate Services And Beans
Implement Dependency Container Service

In this Part we are covering the first 2 sub task - Creating the project and scanning all classes in the application.

Scanning the classes is little tricky since there are 2 ways of running a java app - from .jar file and from directory (calling the main class).

So in this video I am showing how to scan classes both from jar file and from a directory.
