// CFastString class
// 
// Purpose: Speed-Optimized String class
//          The Microsoft CString class is optimized for low memory consumption but not for speed.
//          If a CString has 1000 Bytes and you append 30 Bytes it will reallocate 1030 Bytes.
//          CFastString duplicates the memory each time more memory is required and so avoids unnecessary reallocations
//          Allocating memory on the heap is slow and should be avoided where ever possible
//
// Tipp:    To understand what's going on in CString study the source code in STRCORE.CPP
