Detailed Description

provides an exception-safe way to manage locks in Qore, only to be used on the stack, cannot be dynamically allocated

Ensures that locks are released by locking the lock when the object is created and releasing it when the object is destroyed. Also allows the lock to be released before the object's destruction at the expense of one extra byte on the stack compared to the AutoLocker class.
