    <h1>by_marks()</h1>
    <p>
      Returns an array of event IDs of all events being members of the requested event group.
      These are events which had previously been added to that event group 
      by calling the <code lang="nksp">set_event_mark()</code> function.
      The <code>by_marks()</code> function acts as placeholder for all event
      IDs of the particular group and allows to manipulate a set of events
      this way with only one call.
    </p>
    <p>
      After notes died, this function may still return those recently died
      notes' IDs for a certain while, that means for example that
      <code lang="nksp">num_elements(by_marks($MARK_1))</code> may return a higher
      value than the actual amount of currently active notes. This does not
      mean that you have to remove dead notes from their groups by calling
      <code lang="nksp">delete_event_mark()</code>. The sampler automatically
      removes dead notes from their groups automatically after a certain
      amount of time, and in practice this lag does not have any negative impact
      on using this function, since all built-in functions automatically 
      detect invalid IDs and are automatically ignoring IDs of dead notes.
