/* For those who are familiar with object oriented programming (OOP), the author of this library
* created a Quadrature class with a position function. For those who are unfamiliar with OOP, what 
* means is that in order to use the functionality provided by Quadrature.h, you must first instantiate,
* or create a Quadrature instance. Think of it as declaring a variable, except with greater complication. 
* You must give a set minimum and a set maximum. After you've created an instance of the Quadrature class,
* you can ask the Quadrature instance "questions". For example, quad1.position() returns the position of 
* that particular Quadrature instance.
