Started a unit test directory, with the intention of following test-driven development as much as possible.  I propose we try to use the py.test framework instead of Python's built-in unittest framework, because py.test looks like it's considerably easier and faster to use.
Started a directory for other code/docs/whatever that we use as resources in the project.  Right now the subdirectory contains a clone of the SMOP project code from GitHub (https://github.com/victorlei/smop).
