Show a color palette in a matrix

This function is very simillar to the show_cols() in 'scales'. The main difference is that this function returns a true ggplot2 object. This allows for further customization.

show_palette(cols, num_rows = "square", label_size = 5,
  font_family = "Times", base_size = label_size, ...)
