CreateAccountingBlobStore returns a new AccountingBlobStore.

AccountingContentStore wraps another ContentStore, but adds tracking so that you can determine how much is stored there.

FileSystemContentStore lives in a local directory on this machine.

NullContentStore swallows all writes but does conform to the ContentStore interface.

ReadHeavyBufferedContentSTore is a ContentStore that writes to disk immediately, but also maintains a least-recently-used cache of file contents.
