// Class representing a dynamic array of CFontDir object ptrs.
// Implemented as a singleton object through the static member
// function GetSingleton.
//
// History:  
//     In the original font folder code (as written for Win95), 
//     this directory list was implemented as a simple derivation 
//     from CIVector<CFontDir> with a single instance allocated 
//     on the heap and attached to the static member variable 
//     CFontClass::s_poDirList.  There was no code to delete
//     this instance so we had a memory leak.  To fix this I've
//     replaced this instance with a true Singleton object.  
//     Class CFontDirList is that singleton.  Memory management 
//     is now correct.
