python_examples cannot run

[Guo Issac]

Hi. Anders.

I reinstall my system to ubuntu 20.04. which is same with yours.

Then all cmake-gui and building passed.

when I run the python_examples. 

belowed issued:

root@cade:/home/tmp/openvoronoi/python_examples# python ./offset/offset_1.py
Traceback (most recent call last):
  File "./offset/offset_1.py", line 1, in <module>
    import openvoronoi as ovd

if I run it by python3, below issued:

root@cade:/home/tmp/openvoronoi/python_examples# python3 ./offset/offset_1.py
  File "./offset/offset_1.py", line 32
    print ovd.version()
          ^
SyntaxError: invalid syntax

So I think it is still some problem with the openvoronoi install process.

below is my make install  printing:

root@cade:/home/tmp/openvoronoi/build# make install

root@cade:/home/tmp/openvoronoi/build#

it looks the install path is:

 /usr/lib/python2.7/dist-packages/openvoronoi.so

if I remove python 2.7 from ubuntu, 

the cmake-gui cannot generate.

Could you help me solve this problem?

[Anders Wallin]

all the examples are written for python2.

I just converted a few examples to python3 - pull requests are welcome..
