Refactor Header Files for Improved Readability and Reduced Risk of Name Collisions

[1090MHz]

Summary

Propose refactoring the header files to improve readability and reduce the risk of name collisions.

Changes Made

• Moved header files from PPL/src to PPL/include/PPL for a more standard project layout.
• Added forwarding headers in PPL/src to maintain backwards compatibility.

Benefits

• Improved Structure: Separates implementation (.cpp) and header (.h) files into distinct directories, aligning with common C++ practices.
• Reduced Risk of Name Collisions: Placing headers in PPL/include/PPL reduces the risk of name collisions, especially for common names like settings.h, log.h, processor.h, texture.h, and action.h. This change necessitates using the include style #include "PPL/dataref.h", clearly distinguishing PPL headers from others.
• Improved Readability: Using #include "PPL/dataref.h" makes it clear which library the header belongs to, improving code readability and reducing ambiguity.
• Backwards Compatibility: Forwarding headers ensure existing projects referencing these headers remain functional.

Context

Previously, users might have been adding PPL/src as an include directory and using statements like #include "dataref.h". This approach can lead to ambiguity and potential name collisions. By refactoring the project to use PPL/include/PPL, it becomes clear which library the headers belong to, and it aligns with common C++ practices.

I believe these changes will improve the readability of the code and reduce the risk of name collisions.
