   functions including rw30(). The x column is now the first dimension of a 2D/3D random walk.

New Features

1. Fix #105 - Add internal function rand_walk_column_names() to generate
   column names for random walks.
2. Fix #142 - Add vector function confidence_interval() to generate confidence
   interval tibble.
3. Fix #71 - Add function subset_walks() to subset random walks by max or min
   value.
