I have a column that contains multiple values.  I would like to be able to flatten these values.
Ex: 
Document ID      Author(s)
12                         Bob^Sally
13                         Bob
14                         Fred^Ann^Sally
I would want the output to be:
Document ID      Author(s)
12                         Bob
12                         Sally
13                         Bob
14                         Fred
14                         Ann
15                         Sally
