added a design for adding to do items and an activity to add todo items
some what functional for assignment #2
 	- added the array adapter and implemented the getView 
	- made a custom list item with iconized lists based on current time and
3 days of grace period
 	- provided a way to add items into the list (AddTodoActivity)
- Added a time duration for TaskItem
- Added new icons
- Modified the color code calculation so that it considers Task Duration
fixed the form layout a little bit
some more layout fixes
- Added validation for empty title, preventing empty titles
changed the button to from discard -> ok
Added the colored icons for different screen size and resolution
fixed the layout to add description at the bottom of the todo title
modified some layout on the list item to add time and todo description
fixed the layout on the list row
modify the text sizes on the list, add margin on title to provide space
for long titles
Added a more advanced warning system, now the use will enter the grace
period by him/her self

e.g.
  -- if a todo item is to be completed by ( M/D/Y H:M ) 10/03/2013 03:00
and if the Todo item consumes(Duration) 1 Hour and a Grace period of 1
Hour
  
-   the Icon will be green if current time is before 10/03/2013 01:00 
-   the Icon will be orange if current time is in between 10/03/2013
01:00 and 10/03/2013 02:00
-   the Icon will be red if the current time is after  10/03/2013 02:00,
since the todo item would take (1hr) an hour for completing the todo,
causing overdue and making the todo item to be completed after
10/03/2013 03:00
