This builds up a basic char array object in C with some Python trappings for handling construction and cleanup of the object. Otherwise provides no interface for accessing this object in Python. Since it's purpose is merely to manage a block of memory requested by the user to be passed off and used by other objects that implement the buffer protocol, there is no need for it to have other functionality. It simply allocates memory from Python's memory allocator and frees it on cleanup. Implements the buffer protocol in Cython for this object. Thus allowing the memory allocated to be reused by NumPy arrays or other Python objects that support the buffer protocol.
