Function FindCloseNodes(snap: single): integer;
Identifies all nodes, which are positioned closer to each other than specified in snap (km or miles according to unit). The result is written to GIS file "closenodes". The format of the GIS file is determined by property GISformat.
Close nodes are often an indication of problems in the network, e.g. missing "snap".
The function may identify some of the same problems as the other network checking routines (NodeLinkCheck in particular) and doing a simple check for very short links is always a good idea, before running the routine, since these can trigger many "false" problems.
The generated file will contain the distance between the nodes. If the 2 nodes are connected directly by a link, they are not part of the output.
