NumberPicker

open class NumberPicker

This class has been pulled from the Android platform source code, its an internal widget that hasn't been made public so its included in the project in this fashion for use with the preferences screen; I have made a few slight modifications to the code here, I simply put a MAX and MIN default in the code but these values can still be set publicly by calling code.
