1. Fixed circular dependencies between header files using forward declarations:

    - Resolved circular dependencies between neuron.h and neuron_reference.h
    - Fixed Direction vs NetworkDirection name conflicts
  2. Made const-correctness fixes:
    - Updated method signatures to properly mark const methods
    - Updated parameter types to match function declarations
  3. Fixed template and inheritance issues:
    - Fixed template specialization and implementation
    - Corrected method overrides and abstract class implementations
  4. Fixed relation initialization:
    - Updated relation constructors to use proper parameters
    - Fixed handling of abstract classes in collections (std::vector)
  5. Fixed naming conflicts:
    - Renamed Direction to NetworkDirection
    - Fixed include paths for different component hierarchies
  6. Fixed file I/O operations:
    - Simplified read/write operations that were using undefined methods
  7. Added missing method implementations:
    - Added implementations for methods declared in header files but missing from source files
