        .SYNOPSIS
        Gets metadata about items in an asset directory.
 
        .DESCRIPTION
        The `Get-ProGetAsset` function gets metadata from ProGet about assets. Pass the name of the root asset directory to the `DirectoryName` parameter. Information about all the files in that asset directory is returned. If the URL to an asset directory in ProGet is `https://proget.example.com/assets/versions/subdirectory/file`, the directory parameter is the first directory after `assets/` in this example `versions`, The path parameter the rest of the url in this case `subdirectory/file`.
 
        If you also pass a value to the `$filter` parameter, only files that match `$filter` value in the directory will be returned. Wildcards are supported.
 
        Pass a ProGet session object to the `$Session` parameter. This object controls what instance of ProGet to use and what credentials and/or API keys to use. Use the `New-ProGetSession` function to create session objects.
 
        .Example
        Get-ProGetAsset -Session $session -Path 'myAsset' -DirectoryName 'versions'
         
        Demonstrates how to get metadata about an asset. In this case, information about the `/versions/myAsset` file is returned. if `myAsset` is a directory then all files in that directory will be returned
 
        .Example
        Get-ProGetAsset -Session $session -Directory 'versions/subdirectory'
         
        Demonstrates how to get metadata from all files in the `versions/subdirectory` asset directory. If no files found an empty list is returned.
