A method has been added to export a triangulation to a QgsMesh instance, with the possibility to construct mesh layer with triangulation from existing points and lines. This is the first step to allow the ability to obtain a QgsMesh from other map layers.
The Triangulation and DualEdgeTriangulation classes were also renamed and refactored to make them more consistent with QGIS code.
