# Naive binary search tree implementation, but illustrates my point
# that one of the key elegances of recursive algorithms
# is that the 'shape' of the code closely matches the 'shape'
# of the data.
# 
# So the definition of a binary search tree is either 
# a) it's empty (nil in the ruby example)
