--- A system which provides the ability to read and write files. There are no standard IO natives
-- so this system relies on an exploit which ended up being sanctioned by Blizzard, and because of this
-- there are some caveats.
-- 
-- - All files are confined to the `Documents\Warcraft III\CustomMapData` folder.
-- - The only allowed file extensions are `.txt` and `.pld`.
-- - Generated files contain boilerplate JASS code.
-- - You cannot delete files but you can empty their contents.
-- 
-- @example ```ts
-- // Write to the file
-- File.write("data.txt", "Hello world!");
-- 
-- // Read it's contents
-- const contents = File.read("data.txt");
-- 
-- // Display the contents
-- if (contents) {
--  print(contents);
-- }
-- ```
