Support ProgressMeter or other progress logging utiliites such Term.jl? #58

Currently, predefined controls emits message by using @info which will break ProgressMeter. The issue is that the progress meter will no longer stay at the same place as the @info displays. The suggested fix is to wrap the message in rpad such as

@info rpad("my message ...", displaysize(stdout)[2])

However, with the predefined control behavior, it is impossible to wrap the message before @info.
