This is our module for managing photo albums based on a directory. We assume that, given a path, there is an albums sub-folder, and each of its individual sub-folders are theselves the albums. Files in those sub-folders are photos.
The album manager exposes a single function, 'albums', which returns an array of 'Album' objects for each album it contains.
The album object has the following two properties and one method:
- 'name' -- The name of the album
- 'path' -- The path to the album
- 'photos()' -- Calling this method will return all the album's photos
