  multiEncode :: String -> Data.ByteString.ByteString -> Bool ->  Data.ByteString.ByteString 
 
  -- takes a base encoding and a byteString and returns the encoded byteString with its base prefix
  -- Bool is the padding flag (makes a difference only for bases for which padding is standardized)
  
  decodeByteString :: Data.ByteString.ByteString -> Data.ByteString.ByteString 
 
  -- takes a multibase-encoded byteString and decodes it (UTF-8), prefix is used to determine encoding
 
  appendPrefix :: String -> Data.ByteString.ByteString -> Data.ByteString.ByteString 
 
  -- appends a multibase prefix to a byteString without encoding it
 
  removePrefix :: Data.ByteString.ByteString -> Data.ByteString.ByteString 
 
  -- just removes the prefix, be careful not to use it on a non-prefixed byteString
