pmt: The basis of the system for adding features was created and improvements were made.

- The basic header contents of the system, designed to easily add features, were written.
 - The [CLI11](https://github.com/CLIUtils/CLI11) project was included to provide a better experience for the project.
 - Improved logging system.
 - Unnecessary code cleaned.
