Trying a naive implementation in both Ruby and Go.

The implementation:

creates a map of city -> min/max/count/sum
reads the measurements file line by line
sets/updates city key in the map using the line temperature data
loops over the completed city map key/vals, calculating mean using the data then prints the result

Everything is serial.
