updated QueryByProd servlet's searchByProdID() method to allow for all products to display when search box is left empty and search button is selected (written by Bella);
added an if/else to displayProducts.jsp to check for prodList to be null, if so prints an error message, if not runs the search query and displays the tables (Bella's check, modified by Scott);
general display clean-up within jsp: added line breaks to end of table in order to add space between table & footer(), centered & bolded null product list search result error message, moved the header & column html code to follow the null check so it will not display with the error message if product list is null, updated table border setting to include the column & row data with uniformity;
