Title: Update src/koans/13_recursion.clj

Made a separate function for the factorial function applied to bigints.

The reason for this is that the user gets a java.lang.StackOverflowError exception after successfully implementing a solution for a koan.

The koan in question is titled "Simple things may appear simple.", though there are a few more koans after (but they can be solved in the same step as this one).
