Converting poligons and swapping/reordering issue

[cad0p]

Hi @tyrasd,

I had to solve the issue of converting polygons of boundaries for municipalities but I was writing in Python, so I'm sharing here my solution for the need of swapping and reordering Polygons:

I did not create a copy of the json, so this may be useful given your comments here:

osmtogeojson/index.js

Lines 190 to 191 in e05ddb0

	// create copies of individual json objects to make sure the original data doesn't get altered
	// todo: cloning is slow: see if this can be done differently!

Let me know!
