how to return vector of strings?

[Tom Goles]

Hi,
I'm trying to return a vector of character strings from dynamically
loadable c++ function (.oct file). 
For example, if my function is called 'Test' then from octave I'd like
to call it as follows:

octave> a = Test()
a =

Hello
world

octave>


In other words, the vector that gets returned should be the same as if
I simply typed:

octave> a = ["Hello";"world"]
a =

Hello
world

octave>

My problem is that I don't know which octave c++ class i'm supposed to
use to achieve this result. I have string values stored in regular 2-d
c char array and need to copy them to some octave class which will then
be returned to octave.
Any help/examples would be appreciated.
Thanks,
Tomislav Goles

ps. BTW, I have no trouble returning vectors of real numbers from dynamically
loaded functions - for that I used ColumnVector class (as shown in the
oregonator.cc example).
