    .DESCRIPTION
        Get the projects for a given Github user, repository or organization.

        The Git repo for this module can be found here: http://aka.ms/PowerShellForGitHub

    .PARAMETER OwnerName
        Owner of the repository.
        If not supplied here, the DefaultOwnerName configuration property value will be used.

    .PARAMETER RepositoryName
        Name of the repository.
        If not supplied here, the DefaultRepositoryName configuration property value will be used.

    .PARAMETER Uri
        Uri for the repository.
        The OwnerName and RepositoryName will be extracted from here instead of needing to provide
        them individually.

    .PARAMETER OrganizationName
        The name of the organization to get projects for.

    .PARAMETER UserName
        The name of the user to get projects for.

    .PARAMETER Project
        ID of the project to retrieve.

    .PARAMETER State
        Only projects with this state are returned.

    .PARAMETER AccessToken
        If provided, this will be used as the AccessToken for authentication with the
        REST Api.  Otherwise, will attempt to use the configured value or will run unauthenticated.

    .PARAMETER NoStatus
        If this switch is specified, long-running commands will run on the main thread
        with no command line status update.  When not specified, those commands run in
        the background, enabling the command prompt to provide status information.
        If not supplied here, the DefaultNoStatus configuration property value will be used.

    .EXAMPLE
        Get-GitHubProject -OwnerName Microsoft -RepositoryName PowerShellForGitHub

        Get the projects for the Microsoft\PowerShellForGitHub repository.

    .EXAMPLE
        Get-GitHubProject -OrganizationName Microsoft
