# We need to see what an elegant way to handle the following problems :
#  1. How we want to interpret the nodes
#     What operations we want to apply

#  2. How we want to represent the nodes
#     What data structures we want to use

#  3. How we want to traverse the node trees
#     What algorithms on those data structures
