/*!
 * \brief Interface of the service managing dataset meshes.
 *
 * Creation and initialization happen in 3 phases:
 * - a first phase when calling createMesh() where the mesh is created. In
 *   this phase, only the class managing the mesh is created, but they are not
 *   yet usable.
 * - a second phase when calling allocateMeshItems() where the mesh is
 *   allocated and initialized. This corresponds either to reading the mesh
 *   or dynamically creating the entities.
 * - a third phase which consists of partitioning the mesh if the code runs in
 *   parallel.
 * - a fourth phase that allows processing on the created mesh, such as a
 *   sub-division.
