Created radiology_record which display a radiology record and also contains a form for uploading images to the record.
Updated store_image so that it gets the "record_id" session variable so that it can redirect back to the correct radiology_record page.
Created radiology_form.jsp for creating new records.
Started work on create_record.jsp which will actually insert the new radiology_record into the database.

TODO: create a sequence for record_ids.
