/**
* \brief 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.
