Detailed Description

File I/O operations for Micropolis game engine.

Implements file loading and saving functionalities for the Micropolis game engine. It includes endianess conversions for data compatibility between different architectures, loading and saving city files, handling scenario files, and various utility functions to support file I/O operations. It also includes functions to report file operations to the front-end.
