user_inputs.jl
Every user-defined problem has its own namelist/input file called user_inputs.jl. A sample userinputs.jl file with all possible entries (notice that not all entries are necessary). Use # to comment a line. When a line is commented or not explicitaly give, default values will be used. The entries (with default values) are defined in `src/io/modinputs.jl`.
