A PowerShell script to spit out a random Marvel Superhero when called. This is great for random server naming and automation.
#Hat Tip http://www.virtuallyghetto.com/2014/02/having-some-fun-with-marvel-comics-api.html
#Instructions: Aquire a Marvel API key from https://developer.marvel.com and place them in lines 63 & 64. Import this module into a VM build script and call Get-Hero to grab a random Marvel super hero.
#Imported Get-Hash function (credits http://dbadailystuff.com/2013/03/11/get-hash-a-powershell-hash-function/)
