edited format of list items
Made Tweet a Parcelable object.  To do this I changed the profilePicImage member from a Drawable to a Bitmap which is already Parcelable.  I got the code to create a Bitmap from a URL here:  http://stackoverflow.com/questions/8992964/android-load-from-url-to-bitmap
Implemented onSaveInstanceState and onRestoreInstanceState so that when the app changes orientation the list does not change
added new activity for custom search
moved functions which facilitate twitter search from main activity to NetworkHelper class
implemented search in CustomSearchActivity
made main activity finish when customSearchActivity starts
edited layout of custom search screen
program now cleans the search term of invalid characters before searching for it
added message box when no tweets are found in custom search
filtered &amp; to become & in body of tweets
formatted tweets to be more than one line
made main activity pull new tweets every 30 seconds
added automatic updates to custom search screen
