Detailed Description

Abstract base class for actual allocators types.

All subclasses of LowLevelAllocator are singletons, which each provide a singleton() static method to access their unique instance.

Todo:

The LowLevelAllocator API should use pointers of type void* instead of char*, because the type of contained objects is not specified. This would remove the need to reinterpret_cast, which is prone to error.
