> This attribute is relevant only when used within the train component.  We currently have
an inaccurate way of figuring out if a stop has been visited or not. The renderer gets the
row index of the currently active node and marks every node with an index <= current rowIndex,
as 'visited'. 
> There are many flaws with this approach 
> - for one it assumes that stops are ordered (iow, they have a sequential flow). 
> - secondly, the renderer assumes a behavior for the train when it should let the model
drive this behavior. For instance, I need to support a use case, where the train stops are
all enabled by default and user can jump to any stop. In such situations the above algorithm
fails.  
> A 'visited' API on the component allows the model to set the visited state.
