Servo PWM vs "Normal" PWM

This started from a chat in the [https://gitter.im/rwaldron/johnny-five](Johnny Five Gitter) and I thought I'd put some notes together because this comes up relatively often as people run into the terminology confusion that is caused by the Servo Manufacturers adopting the term PWM and it's usage amongst the Arduino community in relation to analogWrite().

This is my attempt at an explanation so if I've made any mistakes then please PR and we can make this better for everyone.

Servo is generally served by PWM support, right?

Sort of - PWM is typically a reference to an on/off duty cycle time - if I set my duty cycle to 50% then my pulses are on for 50% of the time and off for 50% of the time. If it's 10% then it's on 10% of the time, off 90%.
