Build a command handler from the appended cases.
Build a command handler from the appended cases. The returned handler will throw a scala.MatchError if applied to a command that has no defined match.
The builder is reset to empty after build has been called.

Mutable builder for nested Java CommandHandlers where different states should have different command handlers. CommandHandler per state are added with the
matchmethods and finally a CommandHandler is created with ByStateCommandHandlerBuilder#build.Match statements are appended and evaluated in order, the first one to match is used. If no match is found when evaluating the built CommandHandler for a given state a scala.MatchError is thrown.
