Example input/mesh files for the tutorial (#5)

* main driver example.

* component mesh poisson example.

* paraview load macro.

* moved TrainMode train_mode to MultiBlockSolver from ROMHandler.

* GetBasisTag functions now does not belong to classes. GenerateSamples does not require to initiate ROMHandler.

* poisson base sampling example.

* 2d sampling example.

* random sampling example.

* TrainROM example.

* poisson build rom example.

* BuildROM: global operator is assembled only for ROMBuildingLevel::GLOBAL.

* poisson full workflow example.
