/*

 * MProductPlugin is always typedef'd to the latest plugin version

 * This means that plugin writers can always derive from MProductPlugin,

 * and not usually have to worry about it, but you get the BC advantages of

 * versioning. If there is a new version which you don't want to implement when

 * you rebuild your plugin, then just change the declaration to explicitly derive

 * from the old version (eg change "class Cx : public CBase, public MProductPlugin" to 

 * "class Cx : public CBase, public MProductPluginV1"

 *

 * Remember that what you derive from must match the version number in your ecom rss

 * file! (Strictly speaking, the rss version num must be <= the class derived)
