[IETF_ACTN_TOOLS]
First upload of the Feature code of one of the ACTN tool chain in the new repo The code of this repos deals with "ACTN Topo Generator" tool It provides the features to design multi-domain OTN networks graphically and automatically generate ACTN topology data in JSON format that would be further used by another tool "ACTN PNC Simulator". It is used by the use cases of transport private line and transport slicing. Issue-ID: INT-1857 Change-Id: I075bf66da635365260bfc52b0fe13ac3cb69c3c6 Signed-off-by: Jun Sun <john.sunjun@huawei.com>

+Introduction:
+This tool is a plugin of Draw.io desktop application.
+It can automatically generate ACTN topology JSON data from graph.
+
+Installation and initialization:
+1) Extract the draw.io.7z file
+2) Run draw.io.exe in folder draw.io
+3) Click menu Extras->Plugins…
+4) Import the plugin file named "ongen.js"
+5) Click menu Extras->Load Default Settings
+
+Design ACTN multi-domain OTN topology and generate JSON data.
+1) Add network, node, port or link via drag-and-drop or copy-and-paste.
+2) Collapse or expand containers by shortcut "CTRL+J" and "CTRL+K"
+3) Assign the node id of all nodes automatically by clicking the menu Extras->'Auto-assign Node Id'
+4) Export to ACTN JSON data by clicking the menu Extras->'Export as ACTN JSON'.
