The documentation for some methods in the server-related files (config.go, server.go, and listener.go) has been updated to provide more accurate and descriptive explanations of their functionality. Additionally, the New methods for Config and Server objects have been changed to reflect that they create instances of these objects. Some method functionalities like 'setLogLevel' in server.go have been extended for more accurate operation based on the config log level.
All source code files as well as README.md, .gitignore, and various configuration files have been updated with an SPDX license identifier, changing license from CC0-1.0 to MIT. The copyright year has been updated to 2023, and the copyright holder's email address has been corrected from 'winni@neessen.dev' to 'wn@neessen.dev'. An MIT license text file has been additionally added.
This commit introduces the creation of the core server and its components: config loading mechanism, listener setup, and error handling. The provided configuration allows the server to run different types of listeners. Additionally, it includes robust log-level settings to facilitate debugging and operational transparency.
