/**
* Select columns by index and rename them to the provided names. Returns a
* selection helper function that takes a table as input and produces a
* rename map as output. If the number of provided names is less than the
* number of table columns, the rename map will only include entries for the
* provided names. If the number of table columns is less than then number of
* provided names, only the rename map will only include entries that cover
* the existing columns.
* @param {...(string|string[])} names An ordered list of column names.
* @return {Function} Selection function compatible with {@link Table#select}.
* @example table.rename(aq.names('a', 'b', 'c'))
* @example table.select(aq.names(['a', 'b', 'c']))
