I have a vector of integers named 'aa', that could be millions of integers long.
1. I want a verb called "match' that will find any duplicates in 'aa' of a test vector of integers that will be smaller than 'aa' I want 'match' to return the index of the location of the start of each match of the test vector in 'aa' For example: aa =: 20 $ i.10 4 5 6 match aa 4 14 9 10 match aa NB. No match should produce no result.
