    .SYNOPSIS
    Creates a directory, if it doesn't exist.
 
    .DESCRIPTION
    The `Install-Directory` function creates a directory. If the directory already exists, it does nothing. If any parent directories don't exist, they are created, too.
 
    `Install-Directory` was added in Carbon 2.1.0.
 
    .EXAMPLE
    Install-Directory -Path 'C:\Projects\Carbon'
 
    Demonstrates how to use create a directory. In this case, the directories `C:\Projects` and `C:\Projects\Carbon` will be created if they don't exist.
