Add a way for APY (http://wiki.apertium.org/wiki/APY) to keep track of number of words in input and time between sending input to a pipeline and receiving output, for the last n (e.g., 100) requests, and write a function to return the average words per second over something<n (e.g., 10) requests. For further information and guidance on this task, you are encouraged to come to our IRC channel.
