ReaderWriterSpinLock Class
Represents a fast, lightweight reader/writer lock that uses spinning to perform locking. No recursive acquires or upgradable locks are allowed (i.e., all entered locks must be exited before entering another lock).

Remarks
This reader/writer lock uses SpinWait to spin the CPU instead of engaging event based locking. As a result it should only be used in cases where lock times are expected to be very small, reads are very frequent and writes are rare. If hold times for write locks can be lengthy, it will be better to use ReaderWriterLockSlim instead to avoid unnecessary CPU utilization due to spinning incurred by waiting reads.
