Implements a 'Growing Counter' CRDT, also called a 'G-Counter'. It is described in the paper A comprehensive study of Convergent and Commutative Replicated Data Types. A G-Counter is a increment-only counter (inspired by vector clocks) in which only increment and merge are possible. Incrementing the counter adds 1 to the count for the current node. Divergent histories are resolved by taking the maximum count for each node (like a vector clock merge). The value of the counter is the sum of all node counts. This class is immutable, i.e. "modifying" methods return a new instance.
