This is a textbox with two small buttons on the right to increment/decrement the value in the textbox. This class is based on the Ltextbox class. This supports the optional :text attribute that contains an array of strings that is used during on_increment and on_decrement. The :text attribute is optional and if not provided on_increment/on_decrement calls succ! and decc! (decc! is new method added to String in l_others.rb) for Stings. The on_increment and on_decrement events are triggered using the up and down arrow keys and by clicking on one of the buttons.
