Detailed Description

A Layer class that plots individual points in 2-d, and does nothing in 1-d.

Relies on two data object attributes:

   values ----- a (M,N) array of data points, where N is the dimension of the dataset and M is the
                number of data points

   weights ---- (optional) an array of weights with shape (M,); will be used to set the color of points
