Support std::vector<std::string> function parameters in Matlab/Python
We started to use a lot of instances of std::vector<std::string> as input/output parameter of function and methods. We need to properly modify SWIG .i configuration files to make sure that this function can be used in Matlab.
The first step (currently investigated by @nunoguedelha ) is to just instantiate the std::vector<std::string> template during the SWIG bindings generation.
A cleaner way would be to define proper typemaps between std::vector<std::string> and the appropriate data structure in the target language (cell array of strings in matlab, list of strings in python, table of strings in lua).

The StringVector template instantiation can be easily populated with the push_back method, but at least in Matlab I did not find any way of retrieving its contents. I wonder if it something due that should be solved upstream in https://github.com/jaeandersson/swig/blob/matlab/Lib/matlab/std_vector.i or what.
Any knowledge update regarding handling std::vector<T> of generic objects? Thanks in advance!
Like an automatic typemap that converts std::vector<iDynTree::ComplexObject> to a cell array of iDynTree.ComplexObject Matlab objects? To be honest I do not know how to handle that.
I was trying to handle a vector of rotations like std::vector<iDynTree::Rotation>, so I created a template in iDynTree.i as %template(RotationVector) std::vector<iDynTree::Rotation>;
and this enables the use of standard std::vector methods to handle iDynTree::Rotation
