Release the held lock

// Release the held lock
void Graph_ReleaseLock
(
	Graph *g
) {
	ASSERT(g != NULL);

	// set _writelocked to false BEFORE unlocking
	// if this is a reader thread no harm done,
	// if this is a writer thread the writer is about to unlock so once again
	// no harm done, if we set `_writelocked` to false after unlocking it is possible
	// for a reader thread to be considered as writer, performing illegal access to
	// underline matrices, consider a context switch after unlocking `_rwlock` but
	// before setting `_writelocked` to false
	g->_writelocked = false;
