Thanks for the contribution, Johnson.

In general, we try to avoid new macros as they are nasty.  Also, we encourage 
people
to use Google Mock, which is like a superset of Google Test.  Google Mock lets 
you
compare two containers like:

  EXPECT_THAT(my_container, ContainerEq(expected_container));

or (when the container is small):

  EXPECT_THAT(my_container, ElementsAre(1, 3, _, Lt(5)));
  // Element 1 must be 1; element 2 must be 3,
  // element 3 can be anything, and element 4 must be less than 5.

We may even move EXPECT_THAT and friends from Google Mock to Google Test in the
future.  Therefore we don't want to add new macros to do container comparison 
now.

Thanks for the feedback. I wasn't aware of that framework.
