Robot Warehouse

We have installed a robot in our warehouse and now we need to be able to send it commands to control it. We need you to implement the control mechanism.

For convenience the robot moves along a grid in the roof of the warehouse and we have made sure that all of our warehouses are built so that the dimensions of the grid are 10 by 10. We've also made sure that all our warehouses are aligned along north-south and east-west axes.

All of the commands to the robot consist of a single capital letter and different commands are dilineated by whitespace.

Part One

class Timer:
    """Measure time used.

    # Setup timer
    >>> timer = Timer()

    # Access as a string
    >>> timer.print()
    Time elapsed is 0:00:03.
    >>> timer.print()

1. Set up a map of prices for a number of gizmos that you covet. Then produce a second map with the same keys and the prices at a 10 percent discount.

2. Write a program that reads words from a file. Use a mutable map to count how often each word appears. To read the words, simplyy use a java.utils.Scanner:

val in = new java.util.Scanner(new java.io.File("myFile.txt"))
while (in.hasNext()) *process* in.next()

Or look at Chapter 9 for a Scalesque way.

IO-bound concurrency with asyncio and aiohttp.

Rewritten from the previous approach that was using gevent, due to 
http://www.gevent.org/api/gevent.monkey.html which conflicted with
`google.cloud` libs.

`gevent` allows to create pools to manage greenlets.

What are greenlets?
