Declares kantan.csv.CellDecoder and kantan.csv.CellEncoder instances for joda-time types.
Declares kantan.csv.CellDecoder and kantan.csv.CellEncoder instances for joda-time types.
Note that the type for default codecs might come as a surprise: the wrapping Exported is used to lower their
priority. This is necessary because the standard use case will be to import kantan.csv.joda.time._, which
brings both the instance creation and default instances in scope. Without this type trickery, custom instances
and default ones would always clash.
