Density plot for NV fit

1 2	Density.NV.fit.plot(id, normData, ALL.MUs, ALL.VARs, useGroup = NA, DOplot = FALSE, basesize = 14, GrAblack = TRUE, onlySYMBOL = FALSE)

`id`	is a Illuminan id
`normData`	is the normData data object
`ALL.MUs`	matrix with all means from logLikelihoodOfnormData()
`ALL.VARs`	matrix with all variances from logLikelihoodOfnormData()
`useGroup`	if set to a group (eg. "a","b","c" or "d") the row is colored
`DOplot`	if TRUE plot is printed
`basesize`	size of font
`GrAblack`	if TRUE coloring group 'a' in black because we do not use a Indicator variable
`onlySYMBOL`	if TRUE title is only gene SYMBOL
