Calculate the index of sameness for variables in the data frame

1	identity_index(.df, .na_include = FALSE)

`.df`	data frame
`.na_include`	if TRUE, `NA == NA` will return `TRUE`. Otherwise all observations with at least one `NA` will go to `other` column. Default if `FALSE`

data frame with identity index. identical and non_identical columns contatin number of observations where var1 == var2 and var1 != var2 respectively. other column contains number of observations with neither var1 == var2 nor var1 != var2 conditions, e.g. NaNs, NAs etc.
