class QgsMeshCalculator
{
%Docstring
Performs mesh layer calculations.

Mesh calculator can do various mathematical operations
between dataset groups from a single mesh layer.
Resulting dataset group is added to the mesh layer.
Result can be filtered by extent or a vector layer mask
spatially and by selection of times.

Note: only dataset groups defined on vertices are
implemented and supported
