Compute an approximate string distance between character vectors containing authors' names
(of the form "family name, first name").
The distance is a weighted proportion of the differences between (capitalized)
family names and between first name initial letters.
adist_authors(authors, table, weight = c(family = 0.9, name = 0.1))author names to be approximately matched.
lookup table for matching.
weights associated with differences in family names and in first names.
