Coloring and faceting helper for ggplot

This function takes a ggplot object and source data frame, d, and adds manual color and fill scale layers based on cby and clr and/or faceting based on fby and scales. The data frame, d, is passed for determining the levels of the factor cby in d. The cby and fby columns in d must be factors. Like coloring, faceting must be done by a single factor variable, not crossed factors.

colorFacet(g, d, cby, clr, fby, scales)
