The Create New Menu
The Create New menu simply clears the Contact Name and Contact Phone
#
text fields to facilitate adding a new name and number. After making the new
entries, the user must then save the address book with the
Save or Save As
menus. This callback sets the text
String properties to empty strings:
function varargout = New_Callback(h, eventdata, handles, varargin)
set(handles.Contact_Name,'String','')
set(handles.Contact_Phone,'String','')
