Panic: nil pointer in getCellWidth: `t.output.Formatter()` about go-console

Hi,

Thanks for the return, indeed the output wasn't proprely cascaded from Command to Child Scripts instances.
It's solved with the 1.4.1.

Your example work properly now.

To give you more detail of the internal process:

• if you did not defined the Output (or set it to nil) on your instance of go_console.Command, it will generated for you the default ConsoleOutput (calling NewCliOutput(true, nil)).
• if you did defined the Output on your instance of go_console.Command, it will be set as default Output for all childs Script. (note: you still can overwrite the Script output inside your runner func)

ahh. My bad, I managed to fix it: Basically, both script and each of the Scripts within script can have an Output. Setting the script.Output didn't seem to do much, and was panicking. But, setting the output of the individual script item (i.e. script.Scripts[0].Output for instance) actually fixes this problem.

But, it's a bit unusual to have these fields duplicated both on parent and on child object. I was thinking that, if script.Scripts[0].Output is nil, then it would look for a valid Object from its parent, script.Output
