Detailed Description

Defines a partition of a graph (subtree).

Subgraph, by default, allows unlimited rotation (by computing a matrix).

Limited rotation: ----------------- Optionally, Subgraph can model a part that has a limited range of movement such as landing gear. Subgraph::SetRotationLimit( axis, minDegree, maxDegree ) limits the axis and degree of rotation. Subgraph::RotateLimited( Degree ) then does limited rotation according to those stored parameters.

Implementation: --------------- The subgraph is found by a visitor that searches for a node by its name. Then a MatrixTransform is spliced over the found node.
