Since this is a common procedure when counting items in sequences, there is
a specialized function (`merge`) and data structure (`Accumulator`) for it
in the package `DataStructures`. Try a version of the following:
using DataStructures
a = Dict(2 => 5, 3 => 7, 5 => 1)
b = Dict(2 => 3, 3 => 5, 11 => 4)
c = Dict(merge(counter(a),counter(b))
you can also look at the other Accumulator functions, which may be useful
for what you are doing.
