Compare all pairs of records

compare_pairs(
  pairs,
  by,
  comparators = list(default_comparator),
  x,
  y,
  default_comparator = identical(),
  overwrite = FALSE
)

`pairs`	a `pairs` object, such as generated by `pair_blocking`
`by`	variables from `x` and `y` on which to compare the records.
`comparators`	a names list of comparator functions, for the named variables the given functions will be used to compare the records. For the remaining variables the `default_comparator` will be used.
`x`	the first `data.frame`, when missing `attr(pairs, "x")` is used.
`y`	the second `data.frame`, when missing `attr(pairs, "y")` is used.
`default_comparator`	the default comparison function.
`overwrite`	overwrite exiting variables in `pairs`

Returns the pairs object with a column added for each variable in by. The value is the column is given by the return value of the corresponding comparison function.
