Outdated example of C++ API

[tadeas-hejnic]

Is there an existing issue for this?

• I have searched the existing issues and added correct labels.

Please describe the feature you have in mind and explain what the current shortcomings are?

The current example uses the outdated constructor. It describes setting env variables that should only be passed as arguments to the constructor.

Suggested implementation?

AyonApi con = AyonApi(
        "path/to/log_file",
        "your_api_key",
        "http://your.server",
        "project_name",
        "test_site_id"
);

and delete the part about setting up the env variables.

Describe alternatives you've considered:
