This script generates an XML file containing up or down stream Level-12 HUCs from a user specified HUC anywhere in the Contiguous United States (CONUS).
Briefly, the resultant XML file contains the following information:
 "WhereStrings" for selecting HUCs within the National Hydrography Dataset (NHD) using SQL in ArcMap or QTGIS.
 Location of stream outlets "Intersection Points" between Level-12 HUCs.
 A list of Closed Basins within the graph hierarchy.
 A list of NLDAS cell ids for forcing selection.
 Graph selection lists using DFS, BFS and undirected Dijkstra graphs. With distances to CONUS Level-12 HUCs.
"-i", "--huc12id" Level-12 HUC numerical identification i.e. 020502040102 for Slab Cabin Run
"-r", "--reverse" Reverse selection i.e. false (default) selects upstream, true indicates downstream
"-o", "--ofolder" Output folder location
[Windows]: python.exe get_HUC_Graph.py -i 020502040102 -r false -o c:\
[Ubuntu]: python3 get_HUC_Graph.py -i 020502040102 -r false -o \tmp
