williamr@2: Abstract base class for WAP Push Content Handler plug-ins.
williamr@2: 
williamr@2: A WAP Push Content Handler plug-in processes a WAP Push message that contains 
williamr@2: data of a specific media type. A Content Handler plug-in is loaded by a WAP Push Application
williamr@2: Handler plug-in (CPushHandlerBase-derived object), and the message is passed to handle 
williamr@2: through HandleMessageL().
williamr@2: 
williamr@2: A WAP Push Content Handling plugin is implemented as an ECom plug-in object derived from 
williamr@2: the CContentHandlerBase interface.
williamr@2: 
williamr@2: Each Content Handler plug-in should specify the media type that it handles. Content Handler 
williamr@2: plug-ins can handle multiple media types: for example, a plug-in to handle SI messages can
williamr@2: specify it's media type as "text/vnd.wap.si||application/vnd.wap.sic".
