Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(name, *args, &block) ⇒ Object (private)

Note:

When::TM::Position で定義されていないメソッドは処理を @date_time8601 (type: When::BasicTypes::DateTime) または @any_other (type: When::TM::TemporalPosition) に委譲する(両方ともに有効なメソッドは@any_otherを優先する)
