split names and dictionary values into blocks and make matching within corresponding blocks

1 2	matchNamesByBlocks(names, nblocks, dictionary, dblocks, threshold = 0.95, return = "closest")

`names`	name to compare against dictionary
`nblocks`	vector that specifies blocks for names; should have the same length as names
`dictionary`	set of plausible values to chose from
`dblocks`	vector that specifies blocks for dictionary elements; should have the same length as names
`threshold`	threshold value, minimum score to filter out results with
`return`	what values to return from c("closest", "all"). Return type "closest" works much faster and returns only 1 match per name with highest score.
