online reference update liquidcrystal lcd.print to show decimal places required

I suggest we update the liquidcrystalprint to let people know they can set the decimal places.

thus....

lcd.print(data)
lcd.print(data, BASE)
lcd.print(data,decimal places)

eg lcd.print(floatingpointvariable,1)

gives one place after decimal point instead of the default 2 d.p.
