Initial ckin of working code before addition of checkbox.
Added checkbox to head and elements.  Key to getting checkbox to work
was to make them un-focusable.
initial ckin of SimpleList helper class to track checkbox and textview
handles.
Change getter/setter.  Add toString method.
Add onClick and clickable attributes necessary to get onClick method
working.
Lots of changes to add check box and text box info so onClick would
work.  This included lots of changes to SimpleList and new ViewClass
that extends SimpleList class.
Class that extends SimpleClass for use in tracking the checkbox and
textview views.
remove un-needed import.
Works...
* Removed ViewHolder class -- views change so you can't chache textbox
and checkbox views.
* added selectAllClick method and xml to select all checkbox.
selectAllClick method toggles the value of all checkboxes in list and
updates the list view.
* made list static and check to make sure it isn't init'ed before
initializing it so multiple onCreates work.
* onClick uses view passed in because I found you couldn't cache the
view in the list and expect it to be the same between invocations.
Misc. name changes to make code easier to read.
Added code to delete selected items and add an item.
