# Step 1: Establish the layers

# Write a list of the layers here

#  Option 1
# Rides
#-Driver, -Date, Cost, Rider, Rating

# Option 2
# Driver (by ID)
#-Rides
#-Date, Cost, Rider, Rating

########################################################
# Step 2: Assign a data structure to each layer
# Copy your list from above, and write what data structure each layer should have
#  Option 1
# Rides Array
#Hash for each Ride
#Hash includes following keys: #-Driver, -Date, Cost, Rider, Rating

# Option 2
# Array of Drivers (by ID)
#Ride Hash for Each Ride from that driver
#Hash includes following keys: Date, Cost, Rider, Rating

# I think Option 2 might be easier to work with the data for this assignment

#In the end I used this:
# Array of Drivers Hashes
# Each Drivers Hash contains Driver info incl avg rating, total rides, earnings,
# and an Array of Hashes for each ride Driver has completed.

# I found doing it that way made it easy to read and easy to get the data for each individual driver.
# I'm also thinking it would allow for easy modification in the future, if you would want to add more
# data points per driver or per ride, etc.

# Step 3: Make the data structure!

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