/**
 * 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.
