Organize files and folders

[allyssonmacedo]

• Create class with separeted group of functions. And keep them in one file
• In the file that calls the main function, just keep the data pipeline (calling the functions from another file)
• Organize folders structure and separate files inside them
• Organize a file with constants that will be used among the files. Example, a constant with targets (here the build indicators folder will use it and the build models too and build scores).

the reference of the code from another folder isnt recognizing as a package . It will be fixed in the next MR
