Function Get-GitPullRequestLocal {
<#
.SYNOPSIS
Helper function that creates folder, clones single branch based of a GitHub pull request uri

.DESCRIPTION
This function is created to simplify working with pull requests. In order to get all the files on tbe local system in an organized method, I decided to group together these commands.

.EXAMPLE
Get-GitPullRequestLocal -Uri https://github.com/jaapbrasser/SharedScripts/pull/29

Will create a folder in C:\Temp named after the PR number, and clone the specific branch and display the git status
