cppyy time missing

Hi I was looking at this page https://github.com/mattip/c_from_python/blob/master/c_from_python.ipynb, and noticed the cppyy time was missing from the chart at the end and the copy time printing code was commented out too.

The section labelled "In [67]:" has the commented cppyy time.
The section labelled "Out[67]:" has the table with the missing cppyy time.
