+    /*Details: Smooth takes three parameters, the value to smoothed, the filter value (filterVal), and smoothedVal.
+    
+     float  sensVal - the sensor variable - raw material to be smoothed
+    
+     float  filterVal - The filter value is a float and must be between 0 and .9999 say. 0 is off (no smoothing) and .9999 is maximum smoothing.
+     The actual performance of the filter is going to be dependent on fast you are sampling your sensor (the total loop time), so 
+     some trial and error will probably be necessary to get the desired response.
+    
+     smoothedVal    -  Use this for the output of the sensor and also feed it back into the loop. Each sensor needs its own value.
+     Don't use this variable for any other purpose.*/
