Builds an object with options for plotting likert results.

`low.color`	color for low values.
`high.color`	color for high values.
`neutral.color`	color for middle values (if odd number of levels).
`neutral.color.ramp`	second color used when calling `colorRamp` with `low.color` and `high.color` to define the color palettes.
`colors`	vector specifying the colors to use. This must be equal to the number of likert levels.
`plot.percent.low`	whether to plot low percentages.
`plot.percent.high`	whether to plot high percentages.
`plot.percent.neutral`	whether to plot netural percentages.
`plot.percents`	whether to label each category/bar.
`text.size`	size of text attributes.
`text.color`	color of text attributes.
`centered`	if true, the bar plot will be centered around zero such that the lower half of levels will be negative.
`include.center`	if TRUE, include the center level in the plot otherwise the center will be excluded.
`ordered`	reorder items from high to low.
`wrap`	width to wrap label text for item labels
`wrap.grouping`	width to wrap label text for group labels.
`legend`	title for the legend.
`legend.position`	the position for the legend ("left", "right", "bottom", "top", or two-element numeric vector).
`panel.arrange`	how panels for grouped likert items should be arrange. Possible values are `v` (vertical, the default), `h` (horizontal), and `NULL` (auto fill horizontal and vertical)
`panel.strip.color`	the background color for panel labels.
`...`	included for future expansion.
