 PSYNC - Partial/Full Sync Library based on BF and IBF
 =====================================================

+PSync is a C++ library for name synchronization that implements the `PSync protocol

+It uses Invertible Bloom Lookup Table (IBLT), also known as Invertible Bloom Filter (IBF),
+to represent the state of a producer in partial sync mode and the state of a node in full
+sync mode. An IBF is a compact data structure where difference of two IBFs can be computed
+efficiently. In partial sync, PSync uses a Bloom Filter to represent the subscription of
