datplot 1.1.1

Improved error handling in some functions.
Reduced and improved messaging and warning behaviour.
Fixed slight problem in generate.stepsize() where it would not handle same values in min & max dating properly.
Completely updated and redesigned tests.
Removed unnecessary internal function check.number().

datplot 1.1.0

Using either the original calculation (weights) or calculation of year-wise probability is now an option in datsteps() with the argument calc = "weight" or calc = "probability"
There is now an option to calculate the cumulative probability in datsteps() with the argument cumulative = TRUE. This only works with probability calculation instead of the original (weights) calculation.
Significantly improved the efficiency of datsteps().
Change and improve error-handling of scaleweight().
Remove UTF-8 characters from data and other files to comply with CRAN.
Update documentation and add a pkgdown-site.

Change calculation in get.weights() to 1 / (abs(DAT_min - DAT_max) + 1) to get real probability values for each year. This only has a real effect when using a stepsize of 1, as it makes the weight-values usable as "dating probability".
Clean up calculate.outputrows() and scaleweight() somewhat.
