we need to do some git training
clean up code, fit in 80 chars, remove dead code

format code to fit within 80 columns because it is easier to read
  edlab.tc.columbia.edu/files/eye-tracking%20article.pdf

some of the code might be redundant, these areas are marked with TODO

lots of code was commented out, this has been removed to leave behind
  code that actually runs, making it easier to read

remove errant whitespace including trailing whitespace,
  misuse of tabs, and whitespace-only lines
