No ExchangeClient.php file

[kycaver]

Hello. I'm trying to follow the instructions on page:
https://github.com/Heartspring/Exchange-Web-Services-for-PHP/blob/master/README.markdown

I have downloaded the files from my Exchange server. However, I can find no directory that contains the file ExchangeClient.php. Am I missing something?

I did find that the files I downloaded already exist in the wsdl directory. Are these dummy files that I should simply replace with the ones I downloaded (and then make the addition as suggested)?

Thanks for any help you can provide.
