This template initially designed for use with N2G library to produce network 
diagrams based on OSPF link state database of Cisco IOS-XR devices.

This template parses external-lsa only out of output produced by 
"show ospf database external" command.

Caveats:

 - need `ttp>=0.7.0`, `ttp==0.6.0` will not work due to bugs in it
 
Produces this structure for each input datum/device output:
