Concrete buffer allocator that allocates from a user-supplied fixed-size buffer.
This class provides a concrete buffer allocator that implements the Allocator interface, and allocates memory blocks from a fixed-size buffer that is supplied by the user at construction. The allocator can supply memory that can be maximally (default) or naturally aligned.
