So far I use a kwarg verbose (0,1,2,inf) to allow diagnostic information during my computation:

```julia
verbose && println("message here")

```

A more systematic way to handle this is using the Logging module and `@info, @warn, @error, @debug`. How can I structure this in a context of my module?

```julia
module MyModule

using Logging
# my definitions

end

```

so that later when I call

```julia
using MyModule
execute_computation(data; verbose=1)

```

I can have my desired level of logging. (Not sure if this is the standard way to do this kind of things in Julia.)
