Remove commented out line.
Added std.path.dirSeparator to ensure the program works in other os's
Renamed two functions in FileIO API to a clearer name.
Changed getAddonsDir to getAddonDir. Also rename function calls in various addon lua files.
Added classes FileReader and FileWriter.

FileIO class was getting bloated and needed to be split up. These changes will hopefully address it.
Initial fixes for new API.
Made html addon use new API.
Made json addon use new API.
Removed old FileAPI class and references to it.
Added method getLines to FileReader. Also removed openFile method.

Unlike FileWriter, FileReader doesn't need to store a handle to a file. Therefore openFile was removed and each method now takes a fileName as its argument.
Actually remove openFile method this time.
Removed old code in apitest.lua.

This code was used for testing sorting tasks based on filename - later used in the html and json addons.
