# FILE OUTPUT DESIRED:
# aging:
# aging  |total     |age
# aging  |0         |100
# aging  |2         |115
# aging  |3     |1
# aging  |4         |10

# highway:
# highway   | lanes     |   state   |   limit(mph)
# highway   |   4   |   disable |   25
# highway   |   2   |   disable |   245
# highway   |   3   |   disable |   125
# highway   |   2   |   enable  |   255
# highway   |   3   |   disable |   212
# highway   |   8   |   disable |   78

# FILE INPUT EXCERPT EXAMPLE:

# aging 0 100
# aging 2 115
# aging 3 1
# highway 4 disable 25
# highway 2 disable 245
# highway 0 disable 125
