add logout link.do not search for cart documents if the cart is empty.
show selected metadata fields in the cart view and allow them to be removed from said view
added Scriptaculous effects to many of the ajax calls.neat-o!
can now select and save metadata fields from a document and use them when merging across documents in the "cart"
add "cart" information (won't work for others until i commit the backing classes in meetacat servlet...but need to track the changes for this now).
