 * All fields of the raw type are nullable by the nature of GSon parser;
 * but some of them are required, so we want them to be @NotNull in the actual data class,
 * otherwise there is an error in JSon data received from the server
 *
 * So we create Data class assuming that all required fields actually notnull and
 * catch exception if they are not.
 *
 * Probably, these interfaces shouldn't be used outside of GithubApiUtil.createDataFromRaw()
