Comparing different hierarchical linkage methods on toy datasets

This example shows characteristics of different linkage methods for hierarchical clustering on datasets that are "interesting" but still in 2D. The main observations to make are: single linkage is fast, and can perform well on non-globular data, but it performs poorly in the presence of noise.
