  89     @descr          These initialize an instance of a SfxFilterListener class. Created object listen automaticly
  90                     on right FilterFactory-Service for all changes and synchronize right SfxFilterContainer with
  91                     corresponding framework-cache.
  92                     We use given "sFactory" value to decide which query must be used to fill "pContainer" with new values.
  93                     Given "pContainer" hold us alive as uno reference and we use it to syschronize it with framework caches.
  94                     We will die, if he die! see dtor for further informations.
