When a user inputs "superhero (name)" the plug attempts to find the super hero and return his or her's alias or if the user input an alias name to reveal their super hero name.

The user can also input "superhero list" to print out a list or allowed superhero names.

If a user inputs "superhero (invalid name)" the plugin will print and ask the user to print a correct name.

EXAMPLE:

intput -> superhero Batman
output -> Batman alias is Bruce Wayne
