If you are importing a module from a directory other than your
current directory, then the directory is effectively a package.
In order to make a directory into a package, the directory must
contain a file named __init__.py.  

The file __init__.py can be empty or can contain code.  It will be
evaluated the first time (and only the first time) an application
imports the package or something in it.
