Include precip. intensity in function

Both values should be represented.
Although I'm not sure exactly how yet...
Represent probability as bar towards centre of clock
Create drawRainVertex function

Keeps control of those percentages!
Use intensity to set blueness

Resize clock when the browser is resized

Created a setSize(w, h) function to set the size and radii
Triggered by $(window).resize event
Clock identified by canvas id=weather-clock
