// This package defines several top level IO functions for interacting with
// issues and collections of issues.
//
// Examples:
//
//	To check if a folder is spec compliant:
//		...
//		if issues.IsIssue(path_to_folder) {
//			process_issue(path_to_folder)
//		}
//
//	Additionally, to check if a folder is a collection of spec compliant issues:
//		...
//		if issues.IsIssueCollection(path_to_folder) {
//			process_collection(path_to_folder)
//		}
//
//	To write an [Issue] object to disk:
//		...
//		// NOT IMPLEMENTED
//
//	To remove an [Issue] object from disk:
//		...
//		// NOT IMPLEMENTED
