/**
 * DisplayStep object is the visual representation of an existing step in a pipeline, to be displayed in the pipeline sequencer.
 * Note: Can also be used for creation icons in the Toolbox, as long as no reference to an existing step object is assigned.
 * 
 * IMPORTANT: DisplayStep() should only be used to graphically display a certain Step object. 
 * It only contains a reference to an existing object ($reference), and is not the database object itself!
 * General idea: handle real objects privately, only generate DisplaySteps() based on that data, not the other way around.
