<desc>Creates an effect. Returns the effect if successful or <code>nil</code> if not (e.g. because the effect was rejected). If the effect was accepted by another effect which is deleting itself within the same call, the return value is probably <code>nil</code>. Effects can be created on objects, <code>Global</code> and <code>Scenario</code>. This is passed as the first parameter to the effect callbacks.
