Do not use time.clock(), fixes #126.

This needs a Python 2 clutch I think

Yep, what do you propose? There is no adequate non-deprecated function like time.clock in both Python 2 and Python 3.

It'd go for

try:
   from time import process_time # Python 3
except ImportError:
  from time import clock as process_time  # Python 2 

[J08nY]

It'd go for

try:
   from time import process_time # Python 3
except ImportError:
  from time import clock as process_time  # Python 2 

This should now be fixed and ready to merge.

Ta!
