//////////////////////////////////////////////////////////////////
//
// ComponentArray.h: interface for the CComponentArray class.
//
// Class that holds all the components for the application
// Need to call LoadComponents before you can use them
//
// Derived from a vector so you can access the components each
// as it's own CComponentHolder, but takes care of the Loading
// and Unloading itself.
//
// 'Installed Components' are components that haven't been used
// yet by a user, but have been installed on the system.
// The Loading code first loops through all the user's components
// and then sees if it's missing anything that's installed but
// hasn't been used yet.
//
// The reason for a distiction between a Program ID and a Registry
// Key is to support multiple instances of components in the future
// if needed. Each component would be inited from it's own Key. The
// keys could also be used as Stream ID's in a OLE Storage etc...
