* @subsection Input Input
* - \b modelSeries [sight::data::model_series]: model series from which the mesh is extracted.
*
* @subsection Output Output
* - \b mesh [sight::data::mesh]: output mesh extracted from the model series.
* *
* @subsection Configuration Configuration
* Regarding the ouput configuration, either index or type is required. It is possible to mix both of them and their
* order are not relevant.
* Both index and type specify which mesh will be found from the reconstructionDB. The given mesh will then be put in
* the associated output var.
* - \b index (mandatory) : index in the modelSeries of the mesh to extract. Note that the index starts at 0 for the
* first element in the modelSeries.
* - \b type (mandatory) : structure type of the mesh to extract from the source model.
* - \b matching (optional) : regex to match the organ name, that can be used for instance when you have several
* organs with the same structure type. type cannot be applied to an index constraint.
