• derived nodes inherit all messages from their base classes
  
• see reset method for default settings
  
• the list of points can be created by a combination of data file and/or point messages
  
• the data file can be any number of X Y Z coordinate and X Y Z orientation triplets separated by spaces
  
• the set/value/position message establishes the decimal percentage between the first and last points
