Conflict-free Replicate Data Types are data structures that can be replicated across many network nodes and edited independently, making them useful for applications where state has to be syncronized without manual conflict resolution, a cannonical example is a collaborative text editor.
For this Replicated Graph, children of each branch are represented as an RGA.
As with an RGA only two operations are permited: add a node after
a position, and delete a node at a position, although deleting does
not actually removes the node from the list but marks it a Tombstone,
as other nodes can always be inserted after it.
Because each Replicated Graph must have a unique id across the network, it is recommended for this id to be assigned by a coordinating server that keeps track of all replicas.
