Python 3 compatibility

I don't know if you already support python 3, but I noticed the follwing exception when trying to run one of the examples under Python3:

   import nsim
  File "/usr/local/lib/python3.5/dist-packages/nsim/__init__.py", line 5, in <module>
    from . import analyses1
  File "/usr/local/lib/python3.5/dist-packages/nsim/analyses1/__init__.py", line 12, in <module>
    from .pyeeg import (hurst, embed_seq, in_range, bin_power, pfd, hfd, hjorth,
  File "/usr/local/lib/python3.5/dist-packages/nsim/analyses1/pyeeg.py", line 161
    print "Cannot build such a matrix, because D * Tau > N"
                                                          ^
SyntaxError: Missing parentheses in call to 'print'

Thanks for letting me know.
I've fixed this in 081901b and released the new version 0.1.16.
