Cloning an Atlas Map for use in almost identical locations

This use case covers taking an atlas map, with a small number of devices, and then cloning it, and updating the node & interface ID's of the comparable devices at multiple locations. For example, consider the use case where you have 100 small remote offices, all of which have 1 router, 1 switch, and 2 APs.

In this case, first you would simply export out the template map from the atlas (in a .orionmap extension), then the below function could be called 4 times, each time replacing the source info with the info for the matching device in the new location. In this particular example I have just hardcoded the details I want to find and replace, but it it's relatively trivial to add in these details via the SDK, importing from a CSV, etc. (In the code below, I've left in the original strings, to help understand the formatting)

Then, once all the files have been imported, the ImportMapBatch.exe located in "C:\Program Files (x86)\SolarWinds\Orion\Network Atlas\" can be used to do a bulk import once all the files have been created.
