* @class Lockable
* @brief Makes a class lockable for multithreading

*
* Lockable is an interface (an abstract class) intended to
* be derived by any class that need to be run in a multithreaded
* environment. It provides a lock mechanism that protect the object
* from being concurrently accessed and then being corrupted.
* The embedded Lock class is a scoped-lock, ie the lock is
* guaranted during the lifetime of the Lock object.
