Requesting support for smaller distances

[dhivehi]

I found that this doesnt work for very small shapes. Because in the result, coordinates are rounded to 2 decimal places.

So i kindly request you to add a parameter for decimal places which will support feet or meter accuracy.

Coordinates are not rounded to 2, the print output is rounded to 2. I will look at adding a setting for the print precision. In the mean time you could do a fork and just modify Point in graph.py.
