Iterate over an array in groups of a certain size, padding any remaining slots with specified value (nil by default) unless it is false.
E.g.
%w(1 2 3 4 5 6 7).in_groups_of(3) {|g| p g}
["1", "2", "3"]
["4", "5", "6"]
["7", nil, nil]
%w(1 2 3).in_groups_of(2, ' ') {|g| p g}
["1", "2"]
["3", " "]
%w(1 2 3).in_groups_of(2, false) {|g| p g}
["1", "2"]
["3"]
