Create a function to check if the user is requesting help

[MarcosX]

Checking if the user is requesting help is useful in many scripts, so might be a good idea to provide a helper function.

I guess there's a catch here ${1} e ${@} will be relative to the main command (devcli) and not the subcommad create.

create is a old style of subcommands that its actions are not surrounded by a case statement. Because of this every time devcli reads the create (for description or help) it would execute whatever is inside it.

Because of this catch, which makes life more difficult, I suggest we change the style to a more modern one such as devcli tool create -n NAME -d . which means renaming create to tool and adding an action on it.

Does it make sense?

Yes it does, but it raises another question: are all commands supposed to have a case statement? We did this change on our CLI and it seems to work fine even for scripts that don't have a case statement.

I'm fine with changing create to tool, specially because we could add more options, like add a new command to an existing cli, with a nice template including some helpful boilerplate code.
