iPhone style smooth scroll listbox (beta)

iPhone style low friction smooth scrolling listbox. click drag, let go and the list smooth scrolls to a stop. allows 2 values to be stored against a key and either 1 or both to be displayed. long text is shortened to correct lengths with a '...' suffix. context bar on the right lets you know where you are in the list. there is a custom data class behind the scenes and the user control maintains a linked list on the data to provide quick sorting, regardless of physical data order. arrow up/down or mousedown on header/footer for fast scroll. this is beta, so these functions are implemented but not public interfaced: font name/size and colors. enjoy Mike
