jupyter is language agnostic version of ipython notebook
http://jupyter.org/
Ipython notebook is such a good idea that it is being broadened to include 
other languages, so the Ipython name is being changed to Jupyter.

    Pascal's Triangle
    return row for given level
        clear, naive: add slices
        direct calculation

    Project Euler Problem #1        
    Someone else was starting on Project Euler,
    starting with problem #1, 
    so that problem was revisited with 
    direction calculation that avoids iteration.

Given sequence of positive and negative integers,
return slices with greatest and smallest sums.

from toolz.curried import pipe
pipe()

for _ in range(n):  # For when the loop variable is never referenced.
