/**
 * Returns the list of {@link Blob blobs} that start with the given prefix.

 * <p>In the GCS backend there are no directories, just blobs with names. Implicit in the name,
 * however, is a directory structure (e.g. "dir1/dir2/blob.zip"). Therefore, in order to create a
 * directory browsing experience, we need to "unflatten" the blobs into a directory structure.
 *
 * <p>{@link Bucket#list(BlobListOption...)} provides options to help simulate directories by
 * supplying the {@link BlobListOption#currentDirectory()} and {@link
 * BlobListOption#prefix(String)} options. The prefix acts as the current directory for the blobs
 * we wish to fetch.
