Initial commit
Runs on a local video rather than webcam

Note: this causes the browser to hang after a couple seconds of play
Added a second sample demo
Merged both examples to use same index.html for comparison
Using video file rather than webcam

main2.js seems to perform much better
Uninverted the video and cleaned up additional unnecessary code
Refactor: improved performance, more comments

- Removed redundant arithmetic calculations within pixel data loop
- Interval is bound to video state (starts when video is played,
haulted when video is paused)
- Considered using requestAnimationFrame() but performance seems to be
worse
Adjustable threshold value to define what is considered "significant movement"
Removed unnecessary code
Able to detect direction of movement in x coordinate.

Code is still young and needs improvment. Will wait to try out when
there's light because I've been testing in the dark with only the light
from my iPhone :-P
Added a movement gauge

- Completed comments and cleaned up code also.
Updates to shim.js
Isolated movement example
Diff canvas placed programatically and fps upped to 60.
