This project aims to offer some concurrent data structures
currently missing from the JDK:
° SPSC/MPSC/SPMC/MPMC Bounded lock free queues
° SPSC/MPSC Unbounded lock free queues
° Alternative interfaces for queues
° Offheap concurrent ring buffer for ITC/IPC purposes
° Single Writer Map/Set implementations
° Low contention stats counters
° Executor
