+   Functional Description:  
+   This file contains code that takes in quasi-sine wave ADC inputs from the flow meter
+     From the ADC inputs, it calculates the frequency of that sine wave. The frequency is 
+     important in determining the flow rate and velocity for the flowmeter that are outputed
+     to the display.
