File I/O class. This interface can be used manually, but will usually be used from the MFileTools interface, to more closely match standard C file I/O.

API
open
Opens a file stream with the name specified by path. The argument mode should be a string containing one of the following modes:
| mode | description |
|---|---|
| "r" | read only, start at the beginning of the file |
| "w" | write only, erase existing file and start at the beginning |
close
Close a file stream, if open.
