Matthew Tretter 64d95768f8 Extract GeneratedImageCacheFile ... As mentioned in #167, we want to be forward thinking and allow for a hypothetical spec supertype which has the same functionality as an image spec but doesn't require a source file: a generator. To this end, I've renamed `ImageSpec.apply()` to `ImageSpec.generate()` and extracted a `GeneratedImageCacheFile` base class from `ImageSpecCacheFile`, which supports the more general interface of a generator--namely, a `generate()` method with arbitrary args and kwargs.		2012-11-02 00:33:33 -04:00
