Draw a bar-plot with two bars per label (using Rcssplot)

E3PlotBeforeAfter(before, after, rhs.lab = NULL, col.stim = NULL,
  pixel = 0.1, spacer = 0.04, file = NULL, xticks = seq(0, 250, 50),
  maxlim = NULL, legend.x = c(200, 220), legend.y = 0.8, density = 50,
  legend = c("Preliminary", "Final"), main = "", Rcss = "default",
  Rcssclass = "beforeafter")

`before`	- numeric vector with names. First set of values to plot
`after`	- numeric vector with names. Second set of values to plot.
`rhs.lab`	- character vector with names. Labels to display next to the bars.
`col.stim`	- vector with colors.
`pixel`	- numeric
`spacer`	- numeric. Determines empty space between boxes.
`file`	- filename
`xticks`	- numeric vector. Determines values to place on x-axis
`maxlim`	- numeric. rescaling factor
`legend.x`	- numeric vector of length two. Determines the position and size (left and right extemes) of boxes in the legend
`legend.y`	- numberic in range [0,1]. Use to position the legend vertically.
`density`	- numeric. Density of shading lines on one set of boxes
`legend`	- character vector of length two. Text labels describing the two series of numbers.
`main`	- character string. Title for the plot.
`Rcss`	- Rcss object. Used to style the heatmap with Rcssplot.
`Rcssclass`	- character vector. Classes to tune Rcssplot formatting.
