		an external editor or other external tools.
	
	Usage: 
	1.	Select the note which you want to edit on HTML level, then start this script.
		A child note with the HTML will be generated and selected, which you can edit.
	2.	Once editing is finished, let the temporary HTML note selected and then
		execute this script again.
		The edited HTML will be pur back into the originating note and the temporary 
		HTML note will be deleted.

	-- Put HTML into the new temporary note:
	Nc_Note_Content_Set(nDocID, strTempNoteID, strNoteHtml, 0)

	-- Enable HTML syntax highlighting for the temporary note
	Nc_Note_SourceLang_Set(nDocID,strTempNoteID, "html")

	-- Set custom property for recognizing this as a HTML-Temp-note
	-- The value of the custom property is the note the HTML stems from.

	-- Put its content as non-html back into its originating note as html.
	
	-- get the note content
	strNoteContent = Nc_Note_Content_Get(nDocID, strCurNoteID, 0)

	-- strOriginatingNoteID is the ID of the note which this HTML came from.
