/**

*  This class updates the theme dynamically as it is being somehow modified.

*

*  It connects to XUIKON Content Access API and modifies e.g. NT visibility

*  in theme level as user changes appropriate setting in GS. Appropriate CenRep

*  keys are being observed and theme modifications are launched based on changes

*  in those keys.

*

*  @since S60 3.2
