use_data_table facilitates importing the data.table package by handling
up-front some common set-up tasks for using it in your package.
This function does two main things:
Import the entire data.table namespace (with @import).
Block the usage of data.table as a dependency (DESCRIPTION field
Depends); data.table should be used as an imported or suggested
package only. See this
discussion.
