/**
 * Alle Anforderungen sind über $this->_aCheck konfigurierbar. Manche Anforderungen haben dazu noch weitergehende
 * Informationen. Die Struktur dieser Requirementbeschreibungen:
 *
 * array(
 *      'blExec'    => 1,           // obligatorisch: 0 = keine Prüfung, 1 = Püfung wird ausgeführt
 *      'aParams'   => array(...),  // optional, Inhalt ist von jeweiliger Prüfung abhängig
 * )
 *
 * "Desc1": Diese Struktur kann allein eine Bedingung beschreiben. Wenn mehrere dieser Bedingungen
 * nötig sind (z.B. bei unterschiedlichen Bibliotheksanforderungen), kann diese Struktur als
 * Arrayelemente auch mehrfach genannt werden (kaskadierbar). Grundsätzlich sind alle Requirements
 * kaskadierbar, jedoch ergibt dies nicht bei allen Sinn. :) Eine Kaskadierung sieht so aus:
 *
 * array(
 *      array(
 *          'blExec'    => 1,
 *          ...
 *      ),
 *      array(
 *          'blExec'    => 1,
 *          ...
 *      )
 * )
 *
 * Unbedingt zu vermeiden sind Änderungen in der Scriptlogik, da diese bei Updates nur schwer zu übernehmen sind.
