	/// >>>>>>>>>>>>>>>ВАЖНАЯ ИНФОРМАЦИЯ!!!<<<<<<<<<<<<<<<
	/// Данный редактор создан для работы с PublicAPI.
	/// PublicAPI предназначен для разработки сценариев ELMA.
	/// Например, с помощью PublicAPI можно добавить комментарий к документу:
	/// //Загружаем документ
	/// var doc = PublicAPI.Docflow.Document.Load(56);
	/// //Добавляем комментарий
	/// PublicAPI.Docflow.Document.AddComment(doc, "тут ваш комментарий");
	///
	/// Более подробно про PublicAPI вы можете узнать тут: http://www.elma-bpm.ru/kb/article-642ApiRoot.html
	///
	/// Если же вам нужна более серьёзная разработка, выходящая за рамки PublicAPI, используйте
	/// сторонние редакторы кода, такие как SharpDevelop и VisualStudio.
	/// Информацию по запуску кода в стороннем редакторе вы можете найти тут:
	/// http://www.elma-bpm.ru/kb/article-837.html
