Added my TextIoStream class and my TaskFileReader class. Note that TextIoStream can take anything that has a toString function. TaskFileReader cannot yet read dates, but the rest is finished. I need to do a full test instead of my few unit tests. Note that there are some public methods in it that you may find useful.
