Bash script for easier evaluation

[mforets]

In the future we may setup up a bash script (for internal use, but it could be useful to others), that works more or less like this:

$ ./rbench       # display available options

$ ./rbench  ARCH2021_NLN --names      # display names of available benchmarks for this group

$ ./rbench ARCH2021_NLN       # run all models in this group

$ ./rbench ARCH2021_NLN --stop=10      # run models in this group but excluding those which are longer than 10 minutes

$ ./rbench  ARCH2021_NLN --models=SPRE21   # run spacecraft rendez-vous

The motivation is that, whie we have startup.jl scripts for benchmark groups such as ARCH2021_NLN, there's no automated way of selectively running some benchmarks.
