/**
Example of using ArAutoValueConverter(Field type conversion)

・ Mutual conversion of the following types.
・ String
・ Boolean
・ Integer
・ Long
・ Big Decimal
・ ArYoubi ⇒ Enum but special treatment.
・ Enum
・ Date
・ Calendar
・ ArDate

・ Of course, it may not be possible to convert.Returns null if conversion is not possible.Make no exception.
