function New-GitRepository
{
    <#
    .SYNOPSIS
    Creates a new Git repository.
 
    .DESCRIPTION
    The `New-GitRepository` function creates a new Git repository. The `Path` parameter should be set to a directory path. If the path does not exist, it is created and that directory becomes the new repository's root. If the path does exist, it also becomes the root of a new repository. If the path exists and it is already a repository, nothing happens.
 
    .OUTPUTS
    LibGit2.Automation.RepositoryInfo.
 
    .EXAMPLE
    New-GitRepository -Path 'C:\Projects\MyCoolNewRepo'
 
    Demonstrates how to create a new Git repository. In this case, a new repository is created in `C:\Projects\MyCoolNewRepo'.
