Dependency inversion is essential for writing testable, modular and reusable
libraries.

overview
--------------------------------------------------------------------------------

Interface
A set of required attribute names.

Component
An object fulfilling a specific Interface.

Library
A function that generates Components fulfilling a specific Interface.
(A Library's inputs are its dependencies, much like a module's static imports)

Env
A unique mapping from Interface to Component.

Dependency Interface Annotation
Specifying the expected Interface for each of a library's dependencies.

Dependency Adaptation
If a library's dependency interfaces are annotated, then instead of manually
passing the dependencies into the library, a client can provide an Env that
contains components matching those interfaces. This relieves the client of
knowing how to manually gather all of the dependencies.

examples
--------------------------------------------------------------------------------

1) a thoroughly commented unit test running through most of Dippy's API:
Dippy/dippy/test_cheatsheet.py

2) an example image search project structured with Dippy:
Dippy/dippy/example/example.txt

3) the rest of Dippy's unit tests document expected behavior

--------------------------------------------------------------------------------
project conventions
--------------------------------------------------------------------------------

s instead of self
x__y is a mapping from x to y
