# Step 1: Establish the layers
# # In this section of the file, as a series of comments,
# # create a list of the layers you identify.

# There are three main layers:
# Trips_data (hash)
# rides (arrays of hashes in which each single hash represents a single ride )

# Which layers are nested in each other?
# In Trips_data (hash), for each driver there is rides array which represents all rides for that driver.
# Inside rides (array of hashes) there are hashes with information of each ride.

# Which layers of data "have" within it a different layer?
# The trips_data (hash) has rides (array) inside it.
# Also rides (array) has multiple hashes inside it.

# Which layers are "next" to each other?
# the rides(array) layers of each driver(hashes), the details of each ride is inside a hash

########################################################
# Step 2: Assign a data structure to each layer
# Copy your list from above, and in this section
# determine what data structure each layer should have
# trips_data (hashes)
# rides (arrays of hashes)
# each single ride has its own hash
########################################################
# Step 3: Make the data structure!
# # Setup the entire data structure:
# # based off of the notes you have above, create the
# # and manually write in data presented in rides.csv
# # You should be copying and pasting the literal data
# # into this data structure, such as "DR0004"
# # and "3rd Feb 2016" and "RD0022"
