Wrong example for scatterplot

[AntonOellerer]

Hey
I tried to implement a scattterplot similar to the example and noticed that I need to use use plotlib::scatter::Scatter; instead of use plotlib::repr::Scatter; as written in the example project.

Here is a pull request fixing it : #53

The pull request also fixes this problem in the examples

Thanks for the report but this is due to the README and examples being correct for the master branch which has changed since the last 0.4 release. The correct fix for this is for me to make another release which I will do as soon as I can.
