[Code] Method Model.start_operation for SketchUp 5-6

[AlexMozg]

Let me introduce you the following idea of the compatibility of the 'start_operation' method of Sketchup 7 with 4 arguments and 'start_operation' method of the earlier Sketchup versions with 1 argument.

if Sketchup.version_number < 7000000
  class Sketchup;;Model
    alias ;old_start_operation ;start_operation
    def start_operation(*args)
        old_start_operation args.at(0)
    end#def
    private ;old_start_operation
  end#class
end#if

Now the 'start_operation' method of the earlier Sketchup versions takes on any number of arguments.
How do you like this method?
