Detailed Description

vtRoadMap contains a sets of nodes (TNode) and links (TLink) which define a transportation network.

It can be loaded and saved from RMF files, an ad-hoc Road Map Format which is overdue to be replaced by some clean, extensible standard for transportation networks. Unforunately, such a standard does not yet exist.

Find the node closest to the indicated point. Ignore nodes more than epsilon units away from the point.
