Not compatible with python3

When using with python3:

>>> import googleearthplot
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/home/nvidia/.local/lib/python3.6/site-packages/googleearthplot/__init__.py", line 1, in <module>
    from googleearthplot import googleearthplot
  File "/home/nvidia/.local/lib/python3.6/site-packages/googleearthplot/googleearthplot.py", line 26
    print "[PlotLineChartFromCSV] plotting a line chart from csv file:"+filepath
                                                                      ^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print("[PlotLineChartFromCSV] plotting a line chart from csv file:"+filepath)?
