/**
* An example of creating a CLI that takes advantage of the aliases feature.
*
* Aliases provide a means by which you can define additional top level commands
* that simply delegate to actual commands. Often you actually want to leave
* alias definition up to end users and so Airline supports reading in aliases
* from a user configuration file out of the box
*
