Experiment-wide quality control plot of a scored cellHTS object.

1	imageScreen(x, ar = 3/5, zrange, map = FALSE, anno)

`x`	a `cellHTS` object that has already been scored (i.e. containing the slot `score`).
`ar`	the desired aspect ration for the image plot (i.e. number of columns per number of rows)
`zrange`	the range of values to be mapped into the color scale. If missing, zrange will be set to the range of `x$score`.
`map`	a logical value that determines whether an image map should be created using tooltips to indicate the annotation at each position. It only makes sense to set it to `TRUE` when the function is called from `writeReport`, so the default is `FALSE`.
`anno`	optional input giving the annotation information for the mapping. It should be a vector of the same size as `x$score`. See details.

This function creates an image plot that gives an overview of the whole set of score values from the cellHTS object x, x$score. When the annotation mapping is performed, by default, anno is set to:

The content of x$geneAnno$GeneSymbol (or x$geneAnno$GeneID, if the former is not available), if x is annotated;
The position within the plate, if x is not annotated yet.
