moves testing into python, appropriately or not...

W. Trevor King: I dropped Readme1.md from the original 092cecd,
because I had not been cherry-picking its history.  It looked fairly
similar to the "Building a Library of Code you Trust" section of our
current README.

+Building a Library of Code you Trust
+====================================
+
+Suppose we’re going to be dealing a lot with these animal count files,
+and doing many different kinds of analysis with them. In the
+introduction to Python lesson we wrote a function that reads these files
+but it’s stuck off in an IPython notebook. We could copy and paste it
+into a new notebook every time we want to use it but that gets tedious
+and makes it difficult to add features to the function. The ideal
+solution would be to keep the function in one spot and use it over and
+over again from many different places. Python modules to the rescue!
+
+We’re going to move beyond the IPython notebook. Most Python code is
+stored in \`.py\` files and then used in other \`.py\` files where it
+has been pulled in using an \`import\` statement. Today we’ll show you
+how to do that.
+
+Exercises
+=========
+
+Exercise 1
+----------
+
+Make a new text file called \`animals.py\`. Copy the file reading
+function from yesterday’s IPython notebook into the file and modify it
+so that it returns the columns of the file as lists (instead of printing
+certain lines).
+
+Exercise 2
+----------
+
+We’re going to make a function to calculate the mean of all the values
+in a list, but we’re going to write the tests for it first. Make a new
+text file called \`test\_animals.py\`. Make a function called
+\`test\_mean\` that runs your theoretical mean function through several
+tests.
+
+Exercise 3
+----------
+
+Write the mean function in \`animals.py\` and verify that it passes your
+tests.
+
+Exercise 4
+----------
+
+Write tests for a function that will take a file name and animal name as
+arguments, and return the average number of animals per sighting.
+
+Exercise 5
+----------
+
+Write a function that takes a file name and animal name and returns the
+average number of animals per sighting. Make sure it passes your tests.
