This code demonstrates how to connect manually to the Calais API.

In the Main() function there are 4 variables that you can modify:

1) m_CParams - the cparams that would be sent with a request. Feel free to use some 
predefined (m_ParamsMicro, m_ParamsSimple, etc.) or your own. 

2) m_Content - the text on which the service will perform the analysis. Again, you
can use predefined text or your own.

3) m_Licence - use your key here (very important).

4) proxy  - sometimes you might need to define here new proxy like this: 
new WebProxy(address: port), and define NetworkCredential as well (see in the code).
How do you know if you need to define proxy? If you receive the "Proxy Authentication Error" as a response,
this is most likely the reason.

Also, there are two ways to perform the request: REST or SOAP. Just uncomment whichever you want to execute.
