Title: modified the plot_pca_3d example to actually use scikit-learn's pca class

Seems a bit silly that this example does PCA manually using scipy-linalg rather than the scikit-learn PCA class. I left the manual SVD approach in the example it is labelled and commented out.

I also updated the description of this example to be a bit more descriptive about what exactly is being shown.
