Runs the script.
    
      After loading the script code (see AddText
      and AddTextEx methods) Run
      method can be called to run the script.
      Running script means executing of the all global script code and parsing definitions of
      the functions/subs in the text. For many applications this is enough i.e. loading some
      script and executing it. Thus script text is some kind of sequential commands (possibly
      helper/library functions) and the script is executed once in order to do its work.
      Most advanced usage of the Active Scripts is to use Run method only just a preparation
      for later usage. After the method returns (with success status) global functions/subs
      defined in the script can be called randomly by the hosting application (global data
      variables can be accessed too). In this case script acts as a flexible component that
      provides services to the hosting application. Script is not loaded and not reinitialized
      between operations and it works a times faster then in the case of executing the entire
      script for every action.
      Order parameter. Order in which the scripts written in different
      languages  are executed could be important. For example if code in
      one of the scripts refers to routines and variables in another language
      then the referee must be started first. To meet these needs the order
      parameter gives you ability to control the order of the startup sequence:
      0 - will start the scripts in the same order the script engines
      are added. E.g. if you have:
      host.AddEngine("VBScript")
      host.AddEngine("JScript")
      ' Add some code
      host.Run 0
      The code written in VBScript will be started first then the JScript
      code. And if the JScript code calls some functions from the VBScript code
      everything will be ok, but if VBScript code calls functions of the JScript
      code error will occur.
      -1 - Negative order - the last added language will be started
      first and so forth to the first one.
