"Buildbot ran code beautifier."
suppressed the "configure" and "make" steps from all the run_this_example.sh
added run_this_example.sh for EXAMPLES/small_benchmark_run_to_test_very_simple_Earth and EXAMPLES/small_benchmark_run_to_test_more_complex_Earth
put the "make clean ; make all" step back in all the run_this_example.sh scripts because in the case of SPECFEM3D_GLOBE the solver is compiled with static array and loop sizes that depend on the mesh under study
updated some comments in four scripts
Open IMAIN earlier in solver.

This allows any messages printed in the parameter-loader to go to the
correct file.
Refactor mesher's IMAIN initialization to match solver.
moved NUMBER_OF_SIMULTANEOUS_RUNS and BROADCAST_SAME_MESH_AND_MODEL from setup/constants.h to the Par_file
fixed the "STOP NUMBER_OF_SIMULTANEOUS_RUNS <= 0 makes no sense" bug
fixed a comment
renamed a script
modified another comment (which was unsafe for some of the run_this_example.sh scripts, which parse the DATA/Par_file without checking if the line is a comment or not)
added EXAMPLES/view_all_run_this_example_scripts_to_modify_them.csh
updated a comment
updates smoothing tool
updates smoothing and interpolation tool; renames file smooth_weights_vec.f90 to smooth_weights_vec.F90 and adds vectorizations
uses vectorized loops in smoothing tool; renames smooth_sem.f90 to smooth_sem.F90
