My first formula: Squid Proxy Server

[Vincenzo Ciaglia]

Hi all, i've written my very first formula for Ensemble as my starting
point in the Project. It's about Squid Proxy Server. 

It is in Revision 1 and we should start from here to work with other
related services:

In the next days i'll be more than happy to work on more complex
