added some file based commands (ls, pwd, cd.) to the repl, and created this cool colorized ascii img shower, as shown in img. Also finally reached 100hrs on this project, yipee!, some stats: over 100 functions, and over 4.5k lines (only 600 are empty), 57 imports, rougley 50% of functions have doc-strings and typed args, and over 3k word of documentation in the code. 19 classes. All in python.
