/**

 * WMDRM DLA Default UI Plugin

 * Shows wait note, when SetProgress is set to EProcessingDRMHeader or 

 * to EProcessingMeteringChallenge. Removes wait note, if HandleErrorL is

 * called or SetProgress is set to EIdle. Won't handle any errors, but

 * always leaves with KErrNotSupported. Supports user cancellation from

 * wait note. If CCoeEnv isn't available, then wait note can't be shown,

 * but object creation still succeeds.
