createXevaSet does not with with tibble objects

[sgosline]

I ran into the following error creating a Xeva set with tibbles:

## Error in `[<-.data.frame`(`*tmp*`, , w, value = NA) : 
##   replacement has 1 row, data has 0

After much back and forth I determined it was because I was passing in tibbles from the tidyverse package instead of data.frames. Can you please update the documentation/error messages or perhaps update the package to be tidy-friendly?
