+/* 6 Wheel Calibration
+
+ Use this sketch to calibrate the wheels in your robot. 
+ Your robot should drive as straight as possible when 
+ putting both motors at the same speed.
+
+ Run the software and follow the on-screen instructions. 
+ Use the trimmer on the motor board to make sure the 
+ robot is working at its best!

+/**

+
+  textManager.setMargin(margin_left, margin_top):
+    Configure the left and top margin for text
+    display. The margins will be used by 
+    textManager.writeText().
+    Parameters:
+      margin_left, margin_top: int, the margin values
+      from the top and left side of the screen.
+    Returns:
+      none
+    
+  textManager.writeText(line,column,text):
+    Display text on the specific line and column. 
+    It's different from Robot.text() which
+    uses pixels for positioning the text.
+    Parameters:
+      line:int, which line is the text displayed. Each line
+        is 10px high.
+      column:int,  which column is the text displayed. Each
+        column is 8px wide.
+      text:a char array(string) of the text to be displayed.
+    Returns:
+      none
