roll_na_fill

A fast and efficient by-group method for
"last-observation-carried-forward" <code>NA</code> filling.

A set of fast tidy functions for wrangling, completing and
summarising date and date-time data. It combines 'tidyverse' syntax
with the efficiency of 'data.table' and speed of 'collapse'.
