Exercise snippets on windows

[gfardell]

The load command we use in our exercises is:

%load './snippets/01_exA.py'

This doesn't seem to work for me on windows. On windows the %load command can take the path directly not as a string. So this works:

%load ./snippets/01_exA.py

It also seems to work on linux. Possibly a quirk of jupyters magic command parsing?

Tried without the quotes and worked for me too
