+     *  For now we do create RtGithub right here, in the main method.
+     *  Let's implement some sort of "smart" identity that based on
+     *  INPUT_GITHUBTOKEN variable presence inside the environment will
+     *  create corresponding object, either RtGithub (real github instance)
+     *  or MkGithub (mocked github server in memory xml).

+     *  After information is collected (pull request itself, its files,
+     *  and reviews) we can feed it into the model asking what is the quality
+     *  of the following code review.
+     * @todo #2:30min Fetch all the info about pull request we are working with.
+     *  We should fetch all useful information about pull request that we are dealing with:
+     *  title, files (changes), and its author. Let's present this data in JSON/XML format.
+     * @todo #2:30min Formulate action stoppers.
+     *  We should formulate some action stoppers that would not "go further"
+     *  into processing if: pull request is too small (we need a specific number),
+     *  or some other alerts that would be reasonable.
