Detailed Description

A Palette is a set of brushes (or colors) to be used for painting data sets.

The palette class encapsulates a colletion of brushes, which in the simplest case are colors, to be used for painting a series of data sets. When asked for the m-th color, a palette of size n will wrap around and thus cycle through the available colors.

Three builtin palettes are provided for convenience, one with a default set of colors, one with a subdued color selection, one with rainbow colors.

When a palette changes, it emits a changed() signal. Hook up to it, if you want to repaint when the color selection changes.
