Recursion in RimStone is easy

There are two examples posted today showcasing recursion in RimStone:

article-recursion-factorial,
article-recursion-reverse-string.

The first example calculates the factorial of a number, and the second reverses a string.

Note that by default, the recursion depth is capped at 300 for safety, but you can lift that limit to any number by using "stack-depth" clause in set-app statement.
