make metadata field selections only from within the cart
redesign the look and feel - save point.-cart editing is done by clicking individual assessments rather than doing them in batches.-cart status is shown in the search results (but still need a refresh for after adding cart items from search...)
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).
