#
# DESCRIPTION
#   Attempt to "pretty print" the arith expression (just for
#   the hell of it)
#
# NOTES
#   Notic that parenthesis are printed, although they are not
#   explicitly part of the node information. They are derived
#   from the ordering of the tree, instead. If you want to actually
#   *evaluate* the expression, you will have to derive the 
#   parenthetical encoding from the tree ordering.
#
#   Here is an example equation and how it is encoded:
#
#   ((10 + 2) / 3)
#
#          "/"
#         /   \
#       "+"    3
#      /  \
#    10    2
