ldb

LDB supports different CRDT replication models:

• state-based
• delta-state-based
• pure-op-based

Next features:

• implement Delta-state-based replication (as in http://novasys.di.fct.unl.pt/~alinde/publications/a12-van_der_linde.pdf)
• implement new replication model only using join-decompositions (http://haslab.uminho.pt/cbm/files/pmldc-2016-join-decomposition.pdf)
