function Get-BBServerFile

    .SYNOPSIS
    Gets a list of files from a repository.
 
    .DESCRIPTION
    The `Get-BBServerFile` function returns a list of all files in a Bitbucket Server repository.
     
    If you pass a path, the file search will begin at the specified directory relative to the root of the repository. By default, the file search will begin at the root. All file searches are performed recursively and all matching files from all sub-directories will be returned.
 
    If you pass a name, the search will only return that match the criteria. Wildcards are allowed to search for files. Wildcard matching is *not* supported by the Bitbucket Server API, so all files must be retrieved and searched.
 
    .EXAMPLE
    Get-BBServerFile -Connection $conn -ProjectKey 'TestProject' -RepoName 'TestRepo'
 
    Demonstrates how to get a list of all the files `TestRepo` repository.
