 #' @details [import()] attempts to standardize the return value from the various import functions to the extent possible, thus providing a uniform data structure regardless of what import package or function is used. It achieves this by storing any optional variable-related attributes at the variable level (i.e., an attribute for `mtcars$mpg` is stored in `attributes(mtcars$mpg)` rather than `attributes(mtcars)`). `gather_attrs` moves these to the data frame level (i.e., in `attributes(mtcars)`). `spread_attrs` moves attributes back to the variable level.
 #' @param x A data frame.
 #' @return `x`, with variable-level attributes stored at the data frame level.
