Wet string theory - signalling simulator

Think that a network can be thought of as hardware managed by blobs of software.

Every thing is managed by a blob of software represented by an object.

Now group these objects into an array indexed by a name.

Have an associative array of objects.

Index the associative array by a string representing the instance of the object.

  a[ "nodeName" ] = object()

So there you have it.

Example - railway

INPUT:

OUTPUT:

  box A has train 
  box A asks box B: Is Line Clear?
  box B ack and sets block instrument which is reflected back to box A
