QuantumGate::Buffer

QuantumGate::Buffer is a class that represents a memory buffer. It's used to pass data into and out of a QuantumGate instance. QuantumGate::Buffer shares the same underlying implementation (and thus the same interface) with QuantumGate::ProtectedBuffer; the only difference between them is the memory allocator being used.

QuantumGate::ProtectedBuffer uses a special allocator that adds some extra protection to sensitive data in memory (the data gets locked in memory and prevented from being swapped to disk, and the buffer gets wiped (filled with zeros) whenever it's freed).
