00018  * Class MemoryManagerMalloc: default implementation of MemoryManager
00019  * using malloc().
00020  * 
00021  * Typical use of this class is to create 
00022  * MemoryManager* mm = new MemoryManager(sizeof(YourClass)); 
00023  * where YourClass has operators new and delete redefined:
00024  * void* YourClass::operator new(size_t, MemoryManager* mm)
00025  * { return mm->newData(); }
00026  * void YourClass::delete(void*) { } // do not deallocate memory here
00027  * Then, create objects with obj = new(mm) YourClass(), and destroy them with
00028  * delete obj; mm->deleteData(obj);
