PowerShell script to Remove user from SharePoint Group

Here is a small script I created today in PowerShell to delete a particular user from all sites of a particular web application's particular group.
It reads 3 inputs from user.
(1) Web Application URL (2) Group Name (e.g Viewers) (3) User Login Name (domain\userid)


#####################################################################################
# This script reads Web Application URL, Group Name and User Name to delete user from Group from all Sites of Web Application
# Limitations : Only one user id from only one Group of only one Web Application can be deleted

function global:RemoveUser()
