# Step 1: Establish the layers

  # Write a list of the layers here

# Layer 1: root (ride and share)
# Layer 2: Driver ID to rides' data mapping
# Layer 3: Ride information

########################################################
# Step 2: Assign a data structure to each layer

  # Copy your list from above, and write what data structure each layer should have
# Layer 1 = Hash (driver ID)
# Layer 2 = array (rides)
# Layer 3 = hash (ride information)

########################################################
# Step 3: Make the data structure!

    # Setup the data strcture and manually write in data presented in rides.csv
