This sample gives you a replacement for the Newton OS 2.0 ROM protoNumberPicker.
It has more functionality than the built-in ROM proto. 
We recommend that you use this proto wherever you would normally use protoNumberPicker.

NOTE: there are a number of constants defined for protoNumberPicker_TDS. Instead of 
including these in a text file they are defined in the beforeScript of the 
protoNumberPicker. These constants are only used in the implementation of
protoNumberPicker_TDS, they are not required to use the API.


DOCUMENTATION
-------------
We kept the basic API the same as the builtin protoNumberPicker.

Slots
-----

maxValue

	An integer that is the maximum value for the picker. Must be no greater 
	than 100000000. Once the picker is displayed, you may change the value of 
	maxValue using SetValue.


minValue

	An integer that is the minimum value for the picker. Must be no smaller 
	than -100000000. Once the picker is displayed, you may change the value of
	minValue using SetValue.


value

	The current value displayed by the picker. This is an integer number in the
	range 100000000 to -100000000.  Once the picker is displayed, you may 
	change the value using SetValue.


showLeadingZeros

	Controls the display of leading zeros. Set to TRUE to show leading zeros, 
	or NIL to hide them. Once the picker is displayed, you may change the value 
	of showLeadingZeros using SetValue.


showSign

	Controls the display of the +/- sign in front of the number. Set to TRUE to
	display the sign, NIL to hide it. Once the picker is displayed, you may
	change the value of showSign using SetValue.


viewBounds

	Must be set to a value that is large enough to display all the digits and 
	the +/- sign if you set showSign to TRUE.

	The height of the view must be 28 pixels. The width is 23 pixels per digit
	plus 16 pixels if you display the +/- sign.
