Can't run any examples

Description

No example works.

Most of them have an error related to the number of arguments of the plot() function.

Those examples are in the "latest" version of the documentation, hence target the master branch version of the PyGSP. Two options:

• Look at the "stable" version of the documentation and use PyGSP 0.5.1.
• Install PyGSP from github master and follow the "latest" version of the documentation.

Hmm, I think this happened because I installed the github master over the stable version. I just did a clean reinstall and it seems to work now, thanks!
