wblplot
              Plot a column vector data on a Weibull probability plot using rank regression.
censor: optional parameter is a column vector of same size as data with 1 for right censored data and 0 for exact observation. Pass [] when no censor data are available.
freq: optional vector same size as data with the number of occurences for corresponding data. Pass [] when no frequency data are available.
confint: optional confidence limits for ploting upper and lower confidence bands using beta binomial confidence bounds. If a single value is given this will be used such as LOW = a and HIGH = 1 - a. Pass [] if confidence bounds is not requested.
fancygrid: optional parameter which if set to anything but 1 will turn off the fancy gridlines.
showlegend: optional parameter that when set to zero(0) turns off the legend.
If one output argument is given, a handle for the data marker and plotlines is returned, which can be used for further modification of line and marker style.
If a second output argument is specified, a param vector with scale, shape and correlation factor is returned.
