PIPE_STROKE_WIDTH is not used to set lineWidth

[pixelzoom]

For code review #41 ...

In MeanShareAndBalanceConstants.ts:

  PIPE_STROKE_WIDTH: 1,

I expected to see PIPE_STROKE_WIDTH used as the value for lineWidth option, perhaps in PipeNode.ts. But it only appears in 1 place in the entire sim, in PipeNode.ts:

    this.x = pipeModel.x + MeanShareAndBalanceConstants.CUP_WIDTH + MeanShareAndBalanceConstants.PIPE_STROKE_WIDTH / 2;

So I suspect that you're relying on scenery's default lineWidth (1), and that if I changed that lineWidth or PIPE_STROKE_WIDTH, it would break this code.

So recommendations:

• Rename PIPE_STROKE_WIDTH to PIPE_LINE_WIDTH
• Set lineWidth: PIPE_LINE_WIDTH as appropriate for components of PipeNode

Addressed. Closing.
