The default values for S.filter.number and S.family in the
TLSW() function have been changed to T.filer.number and
T.family respectively.
The default value for the plot.CI argument in
plot.TLSW() has now been removed. If a CI was calculated
for the trend, it will be plotted by default, unless the user sets
plot.CI = FALSE. In addition, plot.TLSW() now
warns the user if argument plot.CI = TRUE but no confidence
interval was calculated.
Fixed issue in plot.TLSW() where data was not
displayed in trend plot when confidence interval not requested.
