Allowing any king of folder structure and adding feature to filter modules

[leandroBorgesFerreira]

In this PR:

• Adding feature to filter out modules. filterModules configuration added.
• Enabling any kind of module structure, until now it was only possible to have the modules inside the root folder.
• Changing the logic to calculate the change in the modules.
• Restructure of the code to improve testability. New tests added to the project making development cycle faster.
• Removing filter configuration as it didn't add any value.
