Added new example

-Added a new example file that converts a .doc file to a .txt file and then generates an mp3 based on the .txt file using a text-to-speech Robot.
-Added an example .doc file to use (examples/fixtures/document.doc).
-Added a comment to image_resize.py explaining what that file does.
