Flushot

#
# Combines 2 vectors into a single vector of size av, 
# by applying a binary operation (defined in block) 
# on each element.
#
# Examples:
#   map2([1,2,3], [4,5,6]) { |a,b| a*b } == [4,10,18]
#   map2([1,2,3], [4,5]  ) { |a,b| a+b } == [5,7,nil]
#   map2([1,2],   [4,5,6]) { |a,b| a+b } == [5,7]
