// a ValueSlider is a MonoScene subclass which displays a TextInput item and 
// a horizontal slider with labels indicating the min and max values for it.
// The slider is tied to the TextInput in such a way that the value displayed
// in the TextInput is updated by the position of the slider, and vice-versa.
