    n::Int; demean = true)

Compute the cross correlation between two uncertain values by independently drawing n samples from x and n samples from y, x_draw and y_draw, then computing the cross correlation between those length-n draws. demean specifies whether the respective means of the x_draw and y_draw should be subtracted from them before computing their cross correlation.
