Overview

The Base encoder defines a public interface for all Encoders. To create an actual Encoder, your subclass should implement only these private methods:

token       # the single character encoding name
digits      # the "alphabet" of the encoding (array)
missing     # digit used for missing data
delimiter   # between data points
separator   # between data series
