Node

In several of the topics in this wiki reference is made to tree 'nodes'. These are a collection of attributes stored in an array to represent a node in the tree structure implied by presentation and definition linkbases. A single node can be a leaf or not. The only distinction is that a leaf node does not have any child nodes of its own.

In a strictly object-oriented implementation a node would be implemented in a class. In this code a node is an array with each element of the array representing a property of the node. Most values are those of the presentation arc. The 'children' element is an array of other node arrays indexed by the href to the the element.
