Domain consistent negative extensional propagator.
This propagator implements the compact-table propagation algorithm based on: J. Demeulenaere et. al., Compact-Table: Efficiently filtering table constraints with reversible sparse bit-sets, CP 2016. and (negative tables) on: H. Verhaeghe et al., Extending Compact-Table to Negative and Short Tables. AAAI 2017.
