Comment addressing for last week's PRs on 3D Mesh Read

[lsawade]

• Remove All commented write(IOUT)s in save_arrays_solver.f90
• utilities.hpp edits
  • Add doc strings
  • create single template for read_array that is just ViewType and then create the different template specializations based on that template.
• Updated parameter documentation to avoid unnecessary RST formatting quirks.
• Add documentation for all current read-in structs including the print functions.
• Add execution space to materials/materials.cpp parallel_reduce
• Create an integer array that writes a state of what each elements type is (0,1,2) → (acoustic, elastic, poroelastic)
• redo print functions to message
