Write a Django server that:

• has a view for the index that does two things: if there is output, render it to the browser, and always renders a fresh version of our form
• has a form that just takes in a text line
• has a model that we can save the text line to
• on submission of the form, uses python's subprocess module to pass the submitted text to the cowsay utility and retrieves the output
• re-renders the homepage with a fresh form and the output from cowsay
• backs up a copy of the text the user submitted
• has a page at the endpoint /history that displays the 10 most recent strings submitted
