Feature request: allow for silent/verbose mode

[richelbilderbeek]

Dear MHCnuggets maintainer,

I have written a package to call MHCnuggets from R. However, when I call the predict function, MHCnuggets produces output, which (1) I cannot prevent, and (2) clutters the log files. Taking a look at the code, one can observe that there are no if statements around the output.

I suggest to add a silent/verbose mode, so that it is possible to run MHCnuggets without having output.
