Update  to match README
Improve ruby example for word-count assignment
Improve ruby:bob test suite and example code

The new example has two teenagers: Alice and Bob.

They both have the same functionality. Bob is implemented in the most
straight-forward way possible with an if/else, whereas Alice is
implemented with separate objects to represent each type of answer, and
that response also knows whether or not it can handle a certain type of
input.

This would be a good solution if the code were expected to change or be
extended.
Fix implementation of question in ruby:bob
Reorder ruby:bob example

Make Bob come first (simple, stright-forward) and Alice come afterwards
(slightly over-engineered).
Add tests to ruby:bob

Help force a more robust solution.
Rename expected file name for ruby:bob
Remove extraneous file
simplify code example on anagram
Add ruby:meetup exercise
Refactor ruby:word-count example
Move clojure test out of ruby section
Rename all test files to include slug (Fixes #49)

Go does not run tests in files named test.go, the file name needs to
have a prefix.

That prefix can have a hyphen in it, so until further notice, we'll use
the assignment slug.
Reorder example in ruby:bob
Rename the expected file in ruby:bob

I had named it teenager because I also have an Alice example in there,
but that becomes confusing.
Tweak ruby:phone-number example
Clarify test suite on ruby:point-mutations
Refactor ruby:grade-school
Refactor ruby:word-count
Add test to ruby:beer-song

This is to help catch a sneaky pluralization issue in the verse for 2
bottles.
