* Initial addition of a game exporter * Fix snake state bug, remove test logs, fix final output line being empty * Ignore test JSONL file * Added explanation for design decision on the you key in SnakeResponse * Adjust gitignore to be more generic * Retain consistency in usage of pointer * Re-word explanation to refer to requests instead of responses * Remove unnecessary nil check * Check error returned by WriteString * Change file permissions for output file * Initialise gameexporter regardless of whether output is requested * Print error and exit if export to file fails * Added another comment explaining reasoning around export checks * Fixed broken test due to changed return type
