function Write-PSFMessageProxy
{
<#
    .SYNOPSIS
        A proxy command that allows smoothly redirecting messages to Write-PSFMessage.
     
    .DESCRIPTION
        This function is designed to pick up the alias it was called by and to redirect the message that was sent to Write-PSFMessage.
        For example, by creating an alias for Write-Host pointing at 'Write-PSFMessageProxy' will cause it to redirect the message at 'Important' level (which is written to host by default, but also logged).
         
        By creating those aliases, it becomes easy to shift current scripts to use the logging, without having to actually update the code.
     
    .PARAMETER Message
        The message to write.
     
    .PARAMETER NoNewline
        Dummy parameter to make Write-Host redirection happy.
        IT WILL BE IGNORED!
     
    .PARAMETER Separator
        Dummy parameter to make Write-Host redirection happy.
        IT WILL BE IGNORED!
     
    .PARAMETER ForegroundColor
        Configure the foreground color for host messages.
     
    .PARAMETER BackgroundColor
        Dummy parameter to make Write-Host redirection happy.
        IT WILL BE IGNORED!
     
    .PARAMETER Tags
        Add tags to the messages.
     
    .EXAMPLE
        PS C:\> Write-PSFMessageProxy "Example Message"
         
        Will write the message "Example Message" to verbose.
     
    .EXAMPLE
        PS C:\> Set-Alias Write-Host Write-PSFMessageProxy
        PS C:\> Write-Host "Example Message"
         
        This will create an alias named "Write-Host" pointing at "Write-PSFMessageProxy".
        Then it will write the message "Example Message", which is automatically written to Level "Important" (which by default will be written to host).
