Detailed Description

A Node's Value is dual-purpose: it's a Node's state and its key.

Each Node derivative defines, in turn, a derivative of Node::Value. The base Node::Value is used for sorting and placing Nodes according to priority. As a key, Value has two orders of priority. 1st-order priority is a constant: which level in a subtree this type of Node belongs. 2nd-order priority is dynamically computed for certain specific types of Nodes. In other words, 1st-order is heterogeneous priority, 2nd-order is homogeneous. Net priority of nodes determines optimal order of Nodes in a Graph.

Nodes with equal net priorities still have a defined placement order. A new equal Node should be appended to the oldest equal one (to the right of). That is, within equal siblings, the order is from oldest to youngest.
